@makeworld if you want to argue semantics, then let me be precise:
IQ is pseudoscientific in that it does not do what it claims, it relies on false assumptions and confirmation bias, is routinely advocated for situations it fails miserably at, and lacks any kind of proper scientific basis.
Some guy in the 1910s thinking that something is scientific does not make it so, no matter how popular it becomes.
@georgepotter I mean okay, I think I just disagree. I like this video if you're interested in why: https://www.youtube.com/watch?v=FkKPsLxgpuY
Thankfully we've moved far beyond the 1910s, over 100 years ago. I have no doubt cognitive testing sucked back then.
