1. What is “trivially true” is still true - indeed incontrovertible. So why are you including this under the heading of “fallacy”? As for metacognition, when I’m thinking about my thinking, I am either a) applying a very general heuristic (like “check your working” or “consider alternative perspectives”) or b) testing my reasoning against my pre-existing content knowledge (“that answer can’t be right because it is greater than 180 degrees”). The first sort of metacognition is a body of procedural knowledge that can be very quickly explicitly taught but which will only “stick” when practiced on specific problems in defined knowledge domains. The second is a byproduct of my content knowledge, not separate to it. Metacognition isn’t as mysterious and mind blowing as you imply here. Pretty much all there is to know about how to think better has been packaged into (rather slim) books by de bono, feynman, polya and kahneman. Obviously, this stuff is good to teach students - explicitly. I doubt asking them to think about their thinking about their thinking is going to be a good use of anyone’s time.

2. You can think VERY well about topics you are ignorant about and come up with profoundly wrong conclusions that have disastrous consequences. There are conspiracy theorists in their mum’s basements thinking very hard and very beautifully right now. We all seem to be endowed with an ability to think about all sorts of things that we aren’t experts in and novices CAN sometimes come up with insights that experts have missed. But your opponents would say this proves their point not yours: basic critical thinking, they would suggest, is biologically primary and so does not need to be turned into a school subject. Learning to walk isn’t a “general capability” in the syllabus. “Learning to think critically” needn’t be either.

3. “We” are not pontificating. You’re the one in the pulpit. Is this question meant to be rhetorical? Surely the answer is “educational psychology” or something like that? One or both sides in the debate might be wrong, but it seems pretty clear that this is an empirical question and that it fits into a broad domain of inquiry. If you are saying that “thinking” is so wild and mysterious that it transcends any empirical study, you’ve crossed into the domain of spirituality and metaphysics and probably need to get a new job as an actual pontiff.

4. This is a better point and it can be tested to some extent. I would say that there seems to be at least as much evidence for non-transfer as for transfer. My guess is that some domains transfer better than others (e.g. skill in chess will probably transfer better to Go than skill in scrabble). My other guess is that there is a limit, quickly reached, to the complexity of problems where transferred thinking skills make a difference. (As a grown-up, I’ll have a better chance of successfully rebooting a frozen PlayStation than my infant son, because I’ve done similar procedures with my work computer. But unless I’m a mechanic, we’ll be equally helpless if the car won’t start.)

5. Saying critical thinking can’t be taught isn’t necessarily saying it is fixed and innate. The argument is, rather, that we can get better at critical thinking as we learn more about the discipline we are thinking IN. Doctors are obviously much better at critical thinking about bodily signs and symptoms than engineers of the same IQ. But if you try to teach critical thinking in isolation from content, your impact will max out quickly.

Ellerton’s armoury (if it has anything to do with Ritchart and Perkins) is likely to turn out to be an assortment of useful mnemonics and metacognitive strategies that nudge students towards asking more and better questions. I’m personally doubtful that teaching these generic routines really counts as teaching a distinctive “critical thinking skill”, useful though they may be as scaffolds for student inquiry. I’m also confident that the most way to help students acquire these skills (if you can call them that) would be to show them how to use them via “I do/you do/we do”.

Assessing content knowledge, that is, a student’s ability to encode, store and then retrieve declarative knowledge (under exam conditions) remains the dominant process used to establish a ‘data spread’ or distribution of student academic ability within subject areas.

Add a simple prompt to your AI research assistant such as “identify any limitations in studies x, y & z” to ensure a (paraphrased equivalent) A-level response for that criterion; and you have pretty much all you need for an A-grade education right?
