The Scientific Method Needs to Be Fundamental Education for Everyone January 15, 2019

We have a problem today.  Actually, we have many problems, but most of them boil down to the fact that we lack disciplined thinking.  As a result, we feel justified in believing any damned thing we like, whether or not it makes logical or evidentiary sense.  A common grounding in the scientific method can address that.

I’ll give an example.  I recently advised a PhD candidate on the use of statistics for his dissertation research.  He was planning on doing about 90 t-tests, plus a collection of ANOVAs.  I warned him that his results were likely to have at least a couple of Type I errors.  He replied, “What is that?”

Where is Martin Gardner when you need him?  (Yes, I know he passed away in 2010).  We lack the understanding of basic analytical statistics and how they influence our beliefs.  This is not rocket surgery, folks.  Anyone, and I mean anyone, who is doing primary research for a doctoral degree should understand the implications of their experimental design.

But we can extend belief well beyond that intellectual exercise.  A very large part of the reason many people feel free to believe things that are quite frankly difficult to believe is that belief is often a subjective thing, rather than based on any sort of scientific discipline.

You may argue that what any person believes is legitimate to that person.  Um, no.  Without a methodology of belief, that represents a lie and a cop-out by that person.  “I believe because I feel like it?”  That doesn’t cut the mustard in serious discussion.

So my point here is that everyone’s belief system has to begin with a disciplined foundation.  We believe something to be true because we have objective evidence, and that evidence allows us to formulate a hypothesis that is testable.  The test may be explicit, or it may be supported or rejected based on additional evidence.  But we cannot believe something because we feel like it.  Life doesn’t work that way.

Few of us think this way in determining our beliefs, and that is unfortunate.

You might also argue that this is an amusing stance for me to be taking.  Decades ago, I learned, and internalized, the scientific method as an undergrad psychology student, which some may consider an odd field of study for that discipline.  But as a social science, psychology is probably the best discipline for employing the scientific method.  It meant a lot for me to begin my adult life with a foundation of the scientific method.  Others can benefit too.
