People can claim standardised testing only measures SES without expecting to be challenged on this board, or more generally attribute children resembling their parents to upbringing, without anyone pointing out genes are a massive confounding factor. They can claim the lab leak theory or Hunter Biden’s laptop are debunked without getting any push back. You can claim IQ tests don’t measure anything significant, but no one would say the same about implicit association tests, although there is vastly less evidence supporting the latter.
I have no idea if you consider these to be my ‘pet topics’, but it’s no different to a conservative saying I must be talking about my pet topics of global warming and Covid vaccines. I’m here to fight ignorance, naturally I talk about topics where ignorance is particularly rife.
