EXCERPTS: Scientists like to think that they are objective and unbiased, driven by hard facts and evidence-based inquiry. They are proud of saying that they only go wherever the evidence leads them. So it might come as a surprise to realize that not only are scientists as biased as non-scientists, but that they are often driven as much by belief as are non-scientists. I
n fact they are driven by more than belief: they are driven by faith. Science. Belief. Faith. Seeing these words in a sentence alone might make most scientists bristle and want to throw something at the wall or at the writer of this piece. Surely you aren’t painting us with the same brush that you might those who profess religious faith, they might say?
But there’s a method to the madness here. First consider what faith is typically defined as – it is belief in the absence of evidence. Now consider what science is in its purest form. It is a leap into the unknown, an extrapolation of what is into what can be. Breakthroughs in science by definition happen “on the edge” of the known.
Now what sits on this edge? Not the kind of hard evidence that is so incontrovertible as to dispel any and all questions. On the edge of the known, the data is always wanting, the evidence always lacking, even if not absent. On the edge of the known you have wisps of signal in a sea of noise, tantalizing hints of what may be, with never enough statistical significance to nail down a theory or idea. At the very least, the transition from “no evidence” to “evidence” lies on a continuum.
In the absence of good evidence, what does a scientist do? He or she believes. He or she has faith that things will work out. Some call it a sixth sense. Some call it intuition. But “faith” fits the bill equally.
If this reliance on faith seems like heresy, perhaps it’s reassuring to know that such heresies were committed by many of the greatest scientists of all time. All major discoveries, when they are made, at first rely on small pieces of data that are loosely held. A good example comes from the development of theories of atomic structure.
[...] Faith, at least in one important sense, is thus an important part of the mindset of a scientist. So why should scientists not nod in assent if someone then tells them that there is no difference, at least in principle, between their faith and religious faith? For two important reasons.
Firstly, the “belief” that a scientist has is still based on physical and not supernatural evidence, even if all the evidence may not yet be there. What scientists call faith is still based on data and experiments, not mystic visions and pronouncements from a holy book. More importantly, unlike religious belief, scientific belief can wax and wane with the evidence; it importantly is tentative and always subject to change. Any good scientist who believes X will be ready to let go of their belief in X if strong evidence to the contrary presents itself.
That is in fact the main difference between scientists on one hand and clergymen and politicians on the other; as Carl Sagan once asked, when was the last time you heard either of the latter say, “You know, that’s a really good counterargument. Maybe what I am saying is not true after all.”
Faith may also interestingly underlie one of the classic features of great science – serendipity. Unlike what we often believe, serendipity does not always refer to pure unplanned accident...
[...] Ultimately there’s a supremely important guiding role that faith plays in science. Scientists ignore believing at their own peril. This is because they have to constantly tread the tightrope of skepticism and wonder. Shut off your belief valve completely and you will never believe anything until there is five-sigma statistical significance for it.
Promising avenues of inquiry that are nonetheless on shaky grounds for the moment will be dismissed by you. You may never be the first explorer into rich new scientific territory. But open the belief valve completely and you will have the opposite problem. You may believe anything based on the flimsiest of evidence, opening the door to crackpots and charlatans of all kinds. So where do you draw the line?
In my mind there are a few logical rules of thumb that might help a scientist to mark out territories of non-belief from ones where leaps of faith might be warranted... (MORE - missing details)
