The anaesthetic of familiarity: how our upbringing can blind us to the obvious

In the restored Edwardian school classroom at Auckland's Museum of Transport and Technology (MOTAT) there is a notice on the wall stating 'Do not ask your teacher questions.' Fortunately, education now goes some way in many nations to emphasising the importance of individual curiosity rather than mere obedience to authority. Of course, there are a fair number of politicians and corporation executives who wish it wasn't so, as an incurious mind is easier to sway than a questioning one. As my last post mentioned, the World Wide Web can be something of an ally for them, since the 'winner takes all' approach of a review-based system aids the slogans and rhetoric of those who wish to control who we vote for and what we buy.

Even the most liberal of nations and cultures face self-imposed hurdles centered round which is the best solution and which is just the most familiar one from our formative years. This post therefore looks at another side of the subjective thinking discussed earlier this month, namely a trap that Richard Dawkins has described as the "anaesthetic of familiarity". Basically, this is when conventions are so accepted as to be seen as the primary option instead of being merely one of a series of choices. Or, as the British philosopher Susan Stebbing wrote in her 1939 book Thinking to Some Purpose: "One of the gravest difficulties encountered at the outset of the attempt to think effectively consists in the difficulty of recognizing what we know as distinguished from what we do not know but merely take for granted."

Again, this mind set is much loved by the manufacturing sector; in addition to such well-known ploys as deliberate obsolescence and staggered release cycles, there are worse examples, especially in everyday consumerism. We often hear how little nutritional value many highly processed foods contain, but think what this has done for the vitamin and mineral supplement industry, whose annual worldwide sales now approach US$40 billion!

Citizens of developed nations today face very different key issues to our pre-industrial ancestors, not the least among them being a constant barrage of decision making. Thanks to the enormous variety of choices available concerning almost every aspect of our daily lives, we have to consider everything from what we wear to what we eat. The deluge of predominantly useless information that we receive in the era of the hashtag makes it more difficult for us to concentrate on problem solving, meaning that the easiest way out is just to follow the crowd.

Richard Dawkins' solution to these issues is to imagine yourself as an alien visitor and then observe the world as a curious outsider. This seems to me to be beyond the reach of many, for whom daily routine appears to be their only way to cope. If this sounds harsh, it comes from personal experience; I've met plenty of people who actively seek an ostrich-like head-in-the-sand approach to life to avoid the trials and tribulations - as well as the wonders - of this rapidly-changing world.

Instead, I would suggest an easier option when it comes to some areas of STEM research: ensure that a fair proportion of researchers and other thought leaders are adult migrants from other nations. Then they will be able to apply an outside perspective, hopefully identifying givens that are too obvious to be spotted by those who have grown up with them.

New Zealand is a good example of this, with arguably its two best known science communicators having been born overseas: Siouxsie Wiles and Michelle Dickinson, A.K.A. Nanogirl. Dr Wiles is a UK-trained microbiologist at the University of Auckland. She frequently appears on Radio New Zealand as well as undertaking television and social media work to promote science in general, as well as for her specialism of fighting bacterial infection.

Dr Dickinson is a materials engineering lecturer and nanomaterials researcher at the University of Auckland who studied in both the UK and USA. Her public outreach work includes books, school tours and both broadcast and social media. She has enough sci-comm kudos that last year, despite not having a background in astronomy, she interviewed Professor Neil deGrasse Tyson during the Auckland leg of his A Cosmic Perspective tour.

The work of the above examples is proof that newcomers can recognise a critical need compared to their home grown equivalents. What is interesting is that despite coming from English-speaking backgrounds - and therefore with limited cultural disparity to their adoptive New Zealand - there must have been enough that was different to convince Doctors Wiles and Dickinson of the need for a hands-on, media savvy approach to science communication.

This is still far from the norm: many STEM professionals believe there is little point to promoting their work to the public except via print-based publications. Indeed, some famous science communicators such as Carl Sagan and Stephen Jay Gould were widely criticised during their lifetime by the scientific establishment for what were deemed undue efforts at self-promotion and the associated debasement of science by combining it with show business.

As an aside, I have to say that as brilliant as some volumes of popular science are, they do tend to preach to the converted; how many non-science fans are likely to pick up a book on say string theory, just for a bit of light reading or self-improvement (the latter being a Victorian convention that appears to have largely fallen from favour)? Instead, the outreach work of the expat examples above is aimed at the widest possible audience without over-simplification or distortion of the principles being communicated.

This approach may not solve all issues about how to think outside the box - scientists may be so embedded within their culture as to not realise that there is a box - but surely by stepping outside the comfort zone we grew up in we may find problems that the local population hasn't noticed?

Critical thinking is key to the scientific enterprise, but it would appear, to little else in human cultures. If we can find methods to avoid the anaesthetic of familiarity and acknowledge that what we deem of as normal can be far from optimal, then these should be promoted with all gusto. If the post-modern creed is that all world views are equally valid and science is just another form of culture-biased story-telling, then now more than ever we need cognitive tools to break through the subjective barriers. If more STEM professionals are able to cross borders and work in unfamiliar locations, isn’t there a chance they can recognise issues that fall under the local radar and so supply a new perspective we need if we are to fulfil our potential?

Research without borders: why international cooperation is good for STEM

I've just finished reading Bryan Sykes' (okay, I know he's a bit controversial) The Seven Daughters of Eve, about the development of mitochondrial DNA research for population genetics. One chapter mentioned Dr Sykes' discovery of the parallel work of Hans-Jürgen Bandelt, who's Mathematics Genealogy Project provided a structure diagram perfectly suited to explaining Sykes' own evolutionary branching results. This discovery occurred largely by chance, suggesting that small research groups must rely either on serendipity or have knowledge of the latest professional papers in order to find other teams who's work might be useful.

This implies that the more international the character of scientific and technological research, the more likely there will be such fortuitous occurrences. Britain's tortuous path out of the European Union has led various organisations on both sides of the Channel to claim that this can only damage British STEM research. The Francis Crick Institute, a London-based biomedical research centre that opened last year, has staff originating from over seventy nations. This size and type of establishment cannot possibly rely on being supplied with researchers from just one nation. Yet EU scientists resident in Britain have felt 'less welcome' since the Brexit referendum, implying a potential loss of expertise in the event of a mass withdrawal.

In recent years, European Union research donations to the UK have exceeded Britain's own contributions by £3 billion, meaning that the additional £300 million newly announced for research and development over the coming four years is only ten percent of what the EU has provided - and the UK Government is clearly looking to the private sector to make up the shortfall. It should also be recognised that although there are high numbers of non-British nationals working in Britain's STEM sector, the country also has a fair number of its own STEM professionals working overseas in EU nations.

The United Kingdom is home to highly expensive, long-term projects that require overseas funding and expertise, including the Oxfordshire-based Joint European Torus nuclear fusion facility. British funding and staff also contribute to numerous big-budget international projects, from the EU-driven Copernicus Earth observation satellite programme to the non-EU CERN. The latter is best-known for the Large Hadron Collider, the occasional research home of physicist and media star Brian Cox (how does he find the time?) and involves twenty-two key nations plus researchers from more than eighty other countries. Despite the intention to stay involved in at least the non-EU projects, surveys suggest that post-Brexit there will be greater numbers of British STEM professionals moving abroad. Indeed, in the past year some American institutions have actively pursued the notion of recruiting more British scientists and engineers.

Of course, the UK is far from unique in being involved in so many projects requiring international cooperation. Thirty nations are collaborating on the US-based Deep Underground Neutrino Experiment (DUNE); the recently-successful Laser Interferometer Gravitational-Wave Observatory (LIGO) involves staff from eighteen countries; and the Square Kilometre Array radio telescope project utilises researchers of more than twenty nationalities. Although the USA has a large population when compared to European nations, one report from 2004 states that approaching half of US physicists were born overseas. Clearly, these projects are deeply indebted to non-nationals.

It isn't just STEM professionals that rely on journeying cross-border, either. Foreign science and technology students make up considerable percentages in some developed countries: in recent years, over 25% of the USA's STEM graduate students and even higher numbers of its master's degree and doctorate students were not born there. Canada, Australia, New Zealand and several European countries have similar statistics, with Indian and Chinese students making up a large proportion of those studying abroad.

As a small nation with severely limited resources for research, New Zealand does extremely well out of the financial contributions from foreign students. Each PhD student spends an average of NZ$175,000 on fees and living costs, never mind additional revenue from the likes of family holidays, so clearly the economics alone make sense. Non-nationals can also introduce new perspectives and different approaches, potentially lessening inflexibility due to cultural mind sets. In recent years, two New Zealand-based scientists, microbiologist Dr Siouxsie Wiles and nanotechnologist Dr Michelle Dickinson (A.K.A. Nanogirl) have risen to prominence thanks to their fantastic science communication work, including with children. Both were born in the UK, but New Zealand sci-comm would be substantially poorer without their efforts. Could it be that their sense of perspective homed in on a need that locally-raised scientists failed to recognise?

This combination of open borders for STEM professionals and international collaboration on expensive projects proves if anything that science cannot be separated from society as a whole. Publically-funded research requires not only a government willing to see beyond its short-term spell in office but a level of state education that satisfies the general populace as to why public money should be granted for such undertakings. Whilst I have previously discussed the issues surrounding the use of state funding for mega-budget research with no obvious practical application, the merits of each project should still be discussed on an individual basis. In addition, and as a rule of thumb, it seems that the larger the project, the almost certain increase in the percentage of non-nationals required to staff it.

The anti-Brexit views of prominent British scientists such as Brian Cox and the Astronomer Royal, Lord Rees of Ludlow, are well known. Let's just hope that the rising xenophobia and anti-immigration feeling that led to Brexit doesn't stand for 'brain exit'. There's been enough of that already and no nation - not even the USA - has enough brain power or funding to go it alone on the projects that really need prompt attention (in case you're in any doubt, alternative energy sources and climate change mitigation spring to mind). Shortly before the Brexit referendum, Professor Stephen Hawking said: "Gone are the days when we could stand on our own, against the world. We need to be part of a larger group of nations." Well if that's not obvious, I don't know what is!

Cerebral celebrities: do superstar scientists harm science?

One of my earliest blog posts concerned the media circus surrounding two of the most famous scientists alive today: British physicist Stephen Hawking and his compatriot the evolutionary biologist Richard Dawkins. In addition to their scientific output, they are known in public circles thanks to a combination of their general readership books, television documentaries and charismatic personalities. The question has to be asked though, how much of their reputation is due to their being easily-caricatured and therefore media-friendly characters rather than what they have contributed to human knowledge?

Social media has done much to democratise the publication of material from a far wider range of authors than previously possible, but the current generation of scientific superstars who have arisen in the intervening eight years appear party to a feedback loop that places personality as the primary reason for their media success. As a result, are science heroes such as Neil deGrasse Tyson and Brian Cox merely adding the epithet 'cool' to STEM disciplines as they sit alongside the latest crop of media and sports stars? With their ability to fill arenas usually reserved for pop concerts or sports events, these scientists are seemingly known far and wide for who they are as much as for what they have achieved. It might seem counterintuitive to think that famous scientists and mathematicians could be damaging STEM, but I'd like to put forward five ways by which this could be occurring:

1: Hype and gossip

If fans of famous scientists spend their time reading, liking and commenting at similarly trivial levels, they may miss important material from other, less famous sources. A recent example that caught my eye was a tweet by British astrophysicist and presenter Brian Cox, containing a photograph of two swans he labelled ‘Donald' and ‘Boris'. I assume this was a reference to the current US president and British foreign secretary, but with over a thousand 'likes' by the time I saw it I wonder what other, more serious, STEM-related stories might have been missed in the rapid ebb and flow of social media.

As you would expect with popular culture fandom the science celebrities' material aimed at a general audience receives the lion's share of attention, leaving the vast majority of STEM popularisations under-recognised. Although social media has exacerbated this, the phenomenon does pre-date it. For example, Stephen Hawking's A Brief History of Time was first published in 1988, the same year as Timothy Ferris's Coming of Age in the Milky Way, a rather more detailed approach to similar material that was left overshadowed by its far more famous competitor. There is also the danger that celebrities with a non-science background might try to cash in on the current appeal of science and write poor-quality popularisations. If you consider this unlikely, you should bear in mind that there are already numerous examples of extremely dubious health, diet and nutrition books written by pop artists and movie stars. If scientists can be famous, perhaps the famous will play at being science writers.

Another result of this media hubbub is that in order to be heard, some scientists may be guilty of the very hype usually blamed on the journalists who publicise their discoveries. Whether to guarantee attention or self-promoting in order to gain further funding, an Australian research team recently came under fire for discussing a medical breakthrough as if a treatment was imminent, despite having so are only experimented on mice! This sort of hyperbole both damages the integrity of science in the public eye and can lead to such dangerous outcomes as the MMR scandal, resulting in large numbers of children not being immunised.

2: Hero worship

The worship of movie stars and pop music artists is nothing new and the adulation accorded them reminds me of the not dissimilar veneration shown to earlier generations of secular and religious leaders. The danger here then is for impressionable fans to accept the words of celebrity scientists as if they were gospel and so refrain from any form of critical analysis. When I attended an evening with astrophysicist Neil deGrasse Tyson last month I was astonished to hear some fundamental misunderstandings of science from members of the public. It seemed as if Dr Tyson had gained a personality cult who hung on each utterance but frequently failed to understand the wider context or key issues regarding the practice of science. By transferring hero worship from one form of human activity to another, the very basis - and differentiation - that delineates the scientific enterprise may be undermined.

3: Amplifying errors

Let's face it, scientists are human and make mistakes. The problem is that if the majority of a celebrity scientist's fan base are prepared to lap up every statement, then the lack of critical analysis can generate further issues. There are some appalling gaffes in the television documentaries and popular books of such luminaries as Sir David Attenborough (as previously discussed) and even superstar Brian Cox is not immune: his 2014 book Human Universe described lunar temperatures dropping below -2000 degrees Celsius! Such basic errors imply that the material is ghost-written or edited by authors with little scientific knowledge and no time for fact checking. Of course this may embarrass the science celebrity in front of their potentially jealous colleagues, but more importantly can serve as ammunition for politicians, industrialists and pseudo-scientists in their battles to persuade the public of the validity of their own pet theories - post-truth will out, and all that nonsense.

4: Star attitude

With celebrity status comes the trappings of success, most usually defined as a luxury lifestyle. A recent online discussion here in New Zealand concerned the high cost of tickets for events featuring Neil deGrasse Tyson, Brian Greene, David Attenborough, Jane Goodall and later this year, Brian Cox. Those for Auckland-based events were more expensive than tickets to see Kiwi pop star Lorde and similar in price for rugby matches between the All Blacks and British Lions. By making the tickets this expensive there is little of chance of attracting new fans; it seems to be more a case of preaching to the converted.

Surely it doesn't have to be this way: the evolutionary biologist Beth Shapiro, author of How to Clone a Mammoth, gave an excellent free illustrated talk at Auckland Museum a year ago. It seems odd that the evening with Dr Tyson, for example, consisting of just himself, interviewer Michelle Dickinson (A.K.A. Nanogirl) and a large screen, cost approximately double that of the Walking with Dinosaurs Arena event at the same venue two years earlier, which utilised US$20 million worth of animatronic and puppet life-sized dinosaurs.

Dr Tyson claims that by having celebrity interviewees on his Star Talk series he can reach a wider audience, but clearly this approach is not feasible when his tour prices are so high. At least Dr Goodall's profits went into her conservation charity, but if you consider that Dr Tyson had an audience of probably over 8000 in Auckland alone, paying between NZ$95-$349 (except for the NZ$55 student tickets) you have to wonder where all this money goes: is he collecting ‘billions and billions' of fancy waistcoats? It doesn't look as if this trend will soon stop either, as Bill Nye (The Science Guy) has just announced that he will be touring Australia later this year and his tickets start at around NZ$77.

5: Skewing the statistics

The high profiles of sci-comm royalty and their usually cheery demeanour implies that all is well in the field of scientific research, with adequate funding for important projects. However, even a quick perusal of less well-known STEM professionals on social media prove that this is not the case. An example that came to my attention back in May was that of the University of Auckland microbiologist Dr Siouxsie Wiles, who had to resort to crowdfunding for her research into fungi-based antibiotics after five consecutive funding submissions were rejected. Meanwhile, Brian Cox's connection to the Large Hadron Collider gives the impression that even such blue-sky research as the LHC can be guaranteed enormous budgets.

As much as I'd like to thank these science superstars for promoting science, technology and mathematics, I can't quite shake the feeling that their cult status is too centred on them rather than the scientific enterprise as a whole.  Now more than ever science needs a sympathetic ear from the public, but this should be brought about by a massive programme to educate the public (they are the taxpayers, after all) as to the benefits of such costly schemes as designing nuclear fusion reactors and the research on climate change. Simply treating celebrity scientists in the same way as movie stars and pop idols won't help an area of humanity under siege from so many influential political and industrial leaders with their own private agendas. We simply mustn't allow such people to misuse the discipline that has raised us from apemen to spacemen.
