Getting an informed, balanced political debate about science

What can be done to ensure an informed and balanced public and political debate of Science and Technology?

The Oxford English Dictionary describes science as “…the systematic study of the structure and behaviour of the physical and natural world through observation and experiment.”1 But science is much more than that: most scientists enter the profession, and most scientific research is funded, because they believe science can greatly improve society. Usually, these goals of learning more about the world and improving society are coupled. However, new and cutting-edge research has been raising ever-increasing concerns about whether the research is benefitting or destroying society.

Scientists occasionally argue that their work should be judged on a purely scientific basis without consideration for the ethics and consequences of the research; but this neglects science’s responsibility to the community at large. As issues that affect all of us, it is important that a public debate is held about these topics and that scientists properly engage in it.

I believe there are three main barriers to a reasoned public debate.

Emotional responses blinding a scientific debate

In recent years, there has been an exponential increase in the number of scientific controversies involving ethical issues of “playing God”. These include stem cell research, cloning and genetically modified “Frankenstein” foods. For many people, the initial emotional response is that of disgust2 – something dubbed the “yuk response”. In order to have the more productive debate about the science, consequences and ethics behind the work, we must get past this initial emotional response.

In one study, psychologist Philip Tetlock asked people to comment on the proposal to set up regulated markets to trade organs3. For most people, the response was that of moral outrage at treating sacred body parts as secular commodities to be traded. However, when the debate was reframed to neutralise the moral outrage (e.g. by exploring how organ trading would lead to a greater number of scarce organs being available to save more sacred lives), 40% of people toned down their opposition. Neutralising the moral outrage encouraged people to critically analyse the arguments in the debate and come to a more reasoned decision.

On many scientific issues, the “yuk response” is preventing a reasoned scientific debate from happening in the first place. As scientists, we should not ignore our moral guidance, but we must not allow the debate to be blinded by it.

Ensuring the media covers the debate accurately

The media plays an important role in informing society about issues which may affect them7. However, two factors lead to poor and inaccurate coverage of scientific issues:

1.       To maximise readership, the press likes to present scientific issues as a series of horror stories. We’re told that cloning will lead to designer armies of obedient soldiers and that nanotechnology-robots will turn the entire world into a blob of “grey goo”45. These poignant scenarios lead people to make their mind up before considering the scientific uncertainties, risks and benefits to the detriment of a good debate.

2.       To provide “balanced” coverage, journalists will try to cover both sides of the story. In a political or social dispute, such as whether the UK should join the Euro, it is reasonable that both sides should be treated equally and receive equal press coverage. However, it is inappropriate to treat the arguments of both sides in a “scientific-fact” controversy as equal. For example, the weight of evidence in favour of climate change is much greater than that against. Attempts by journalists to be “balanced” and present both sides equally give an inaccurate impression that there is still a great deal of scientific controversy about climate change6.

Scientists should be aware of the importance of the media in shaping debate and public opinions and that communicating the science can be as important as the science itself.

Engaging the people: Capturing the popular imagination

Because of cultural differences8 between science and art (e.g. science being concerned with truth; art about opinions), scientists tend to avoid the arts. However, given debate is all about opinions, scientists should not be afraid to utilise the arts to catalyse debate about issues of scientific importance.

For example, Dan Brown’s book “The Da Vinci Code” inspired a large amount of “real world” interest, television documentaries9 and archaeological research about the Holy Grail in Christian theology. In the same way, the arts can provoke discussion about important scientific issues10.

The arts will, of course, never replace the rigour of peer-reviewed papers and the scientific process; but as a complement can outline the major issues to the public in an interesting and engaging way without undermining the practice of science itself.


As science affects the whole of society, scientists have a moral obligation to inform, involve and engage the public in a debate about science. This should be achieved by focusing the debate on the important issues, ensuring they are portrayed accurately and inspiring discussion about them.

This essay was originally prepared for an essay writing competition at my college. I have decided to share it here as I feel it could be of interest to regular readers. Comments and thoughts very welcome.

Google Street View: What purpose?

So Google Street View launched here in the UK a few days ago. It’s been controversial: all kinds of odd things have been found (see gallery at The Telegraph, and this rather hilarious sequence of a Street View driver being chased by the police for a traffic offense).

Privacy campaigners have been campaigning to get Street View shut down. That raises the interesting question: what useful purpose does Street View actually serve? How has Street View actually helped you? How has Street View benefitted you in your own every day life?

We all know about the privacy implications of Street View but I think I’ve yet to hear the benefits and the utilities. I hope that’s a discussion we’ll be able to have: without that discussion we can never really weigh up whether Street View is good for society.

I’ll start the list:

  • I wanted to send a letter the other day. The envelope was larger than A4 so I went to three local postboxes: none of them had a large enough slot to allow me to actually put the letter inside. I returned home and then using Street View was able to locate nearby postboxes and actually see whether they would be big enough to accept my letter. I was successful in completing this task with Street View so it probably saved me a lot of time visiting lots of postboxes and trying to find one large enough.

Sky launching 3D television in the UK

According to a Digital Spy report, we could be seeing 3D television in our homes by the end of the year.

Digital television (satellite) broadcaster BSkyB plans to provide the 3D service through its existing Sky HD playout and set top box system. The broadcaster trialed this out first last December and has filmed several sporting events in HD.

Of course, 3D television relies on delivering a slightly different image to each eye. There are several different technologies to do this:

  • Red-Blue Glasses. The oldest and most infamous form of 3D. Normally, all TV pictures are made up of a combination of red, green and blue. In this system, the red channel is used to deliver a picture to your left eye and the blue channel to your right eye. You need to place a red filter over your left eye to eliminate the blue channel and vice versa. It’s great because it works with any screen, but it looks strange and it’s uncomfortable.
  • Polarised Light. The TV set emits light which is orthogonally polarised, depending on which eye it is intended for. For example, vertically polarised light for the left eye and horizontally polarised light for the right eye. By using polarisation filters, each eye only sees the image intended for it. This gives a much nicer image than using red-blue glasses but obviously requires technology in the TV to create polarised light.
  • Sharp’s 3D Display. I was lucky enough to see a demonstration of this a few years ago and to play Quake in 3D. It’s pretty cool. I won’t go into the full details of how it works: but only one person can use the display at once and they have to be sat in the exact right position for the system to work at all.

Sky have, rather sensible, opted for the polarised light system for 3D television.

Perhaps this is the killer application that HD needs.
