The scientific method – what about the philosophical method?

I enjoy the In Our Time Podcasts with Melvyn Bragg. The subjects are very wide-ranging and always informative.

His last one was on The Scientific Method. It basically discusses the evolution of scientific methods from a philosophical viewpoint. The participants were:

• Simon Schaffer, Professor of the History of Science at the University of Cambridge;
• John Worrall, Professor of the Philosophy of Science at the LSE and
• Michela Massimi, Senior Lecturer in the Philosophy of Science at University College London.

Personally, I would have welcomed inclusion of a practising scientist to bring some practical insight into the discussion. Still, I did find the historical survey of philosophers ideas on the scientific method interesting. But it got me thinking – these philosophers seem so concerned about the scientific method – and yet no one talks about the philosophical method!

What is the philosophical method?

What methods do philosophers use? And how have these evolved over time? And why do we never come across critiques of philosophical methods? Is this because philosophers are happier critiquing other areas and avoid their own?

For example. While I thought this discussion did treat the subject fairly the descriptions of scientific method offered by various philosophers over the years do strike me as “just so” stories. I get the feeling that the philosophers concerned are presenting their pet model. Evidence quoted is usually anecdotal, more for example rather than support. The Copernican revolution, or the evolution of Einsteinian mechanics out of Newtonian mechanics are used to illustrate a thesis, rather than testing the hypothesis by analysing the data from the history of a large number of scientific theories.

Now, I could never have got any of my research results accepted for publication with only anecdotal and illustrative evidence. Good data, statistically analysed to show significance for claims, was always expected. The standards for philosophical theories seems to be a lot lower. How many philosophers really take data collection and analysis seriously?

The other thing that strikes me about these “just so” stories are that they always seem to ignore the human factor. Scientific method is often presented as an algorithm or flow chart – scientists behave this way and they produce hypotheses which are checked experimentally, etc.

But scientists are humans. They are just as prone to emotions as any other people. And in fact current scientific understanding of decision-making indicates that emotions are very much involved in our seemingly rational considerations. Where else do scientists get the passion for the work they do? Creativity does not come from mechanical application of methods. And scientists are also prone to prejudice, fantasy,  attachment to preconceived ideas, and confirmation bias as anyone else. The possible consequences of this need to be recognised and scientific methodology must compensate for it.

That’s why I like Richard Feynman‘s description of scientific method as “doing whatever it takes to avoid being fooled by reality.” This is a better description of the human reality of scientific research than any descriptive, or prescriptive, flow diagram of “scientific method.”

Why does this matter?

Well, for two reasons:

1: How often does one read material from opponents of science using pop versions of scientific method and philosophy of science to justify their rejection of, or denial of, scientific knowledge?  Creationists and climate change deniers will often talk about Kuhnian “paradigms” or Popperian “falsification” to justify their rejection of whole fields of science. We even have the ridiculous example of a climate denier group in Australia naming itself The Galileo Movement! They are equating acceptance of the current scientific understanding as equivalent to belief in a geocentric universe! (See “Galileo Movement” Fuels Climate Change Divide in Australia).

2: Post-modernist and ideological motivated concepts of the philosophy of science do get circulated in academic circles.  In the past I have heard some of these descriptions presented by local science managers and suspect that these ideas can influence management and human resources teachings via philosophy of science and sociology of science inputs. The danger is that this influence decisions on science funding and investment.

Maybe some of the cock-ups we have seen in science management and New Zealand over the years could be traced back to ideology and misunderstanding about the nature of scientific research picked up by managers during their training. Maybe not all these mistakes were due to incompetence.
