Why I dislike ‘Critical Thinking’

27 Feb

You’ll see from the title of this blog that I don’t like the phrase ‘critical thinking’, and think that it activity works against encouraging rational thought in students. Ironically, the only time that I tend to use the phrase ‘critical thinking’ is when I’m talking to other academics, otherwise they don’t know what I’m going on about ! In working on a larger piece of work about my view of developing rational thought I’ve hit upon a great example of what I think is wrong with the current critical thinking literature.

If you grab a select of the critical thinking textbooks that will undoubtedly appear in your nearest library you’ll find that the identification of logical fallacies is a consistently addressed topic. With my ‘teacher’ hat on I’ve always found logical fallacies an appealing topic. There are wonderful on-line resources with many engaging examples that will appeal to students and it’s straightforward to design an assessment to measure whether students recognise logical fallacies. The trouble is that when you delve into the rationale for teaching students to identify logical fallacies things begin to unravel.

For anyone who spends their life attending meetings with other academics, the rationale for teaching logical fallacies would seem obvious, as phrases like ‘ad hominem attack’ and ‘that’s just a strawman’ are mainstays of academic ‘debate’. However, we can’t really justify curriculum content based on the ability to win an argument in a Faculty meeting. Which leads me to ask what is the utility of understanding logical fallacies for the average undergraduate ? Surely what we want our students to be able to do is to disentangle the evidence for a particular argument from the rhetorical devices being employed to make that argument, after all it would be perfectly possible for a position that has all the evidence behind it to be proposed with an argument entirely riddled with fallacies.

My own view is that the appearance of logical fallacies in so many critical thinking texts is a products of the roots of critical thinking itself, rather than in any belief in it’s utility for students. Critical Thinking was a product of the academic discipline of philosophy, where the understanding of formal logical is a central skill. Thus , we’ve ended up teaching a topic not because it has directly relevance to our students, but because it is a component of a discipline at least once-removed for m that which we are teaching.

In my previous post here I mused on the teaching of rational thought in the new ‘alternate facts’ world, and it occurs to me that in this ‘New world order’, the teaching of logical fallacies might actually be counter-productive. I could see an argument that a book chapter on logical fallacies could easily be read has ‘how to win an argument even if you don’t have any evidence’.
