To be fair, you have to have a very high IQ to use right wing Twitter.
Something to keep in mind with the endless "smart kid" discourse - and IQ of 120 is about 10% of the gen pop (around 15% of the white/asian pop), and 120 is a common cutoff for "gifted" in schools. Then you think about the type of person who posts in this part of twitter - where you need strong literacy, have interest in abstract arguments/news/philosophy/geopolitics- and you're dealing with a group that almost certainly has a higher percentage of 120 IQs and above than the typical population (both left and right wing people). So yeah, it does stand to reason that this section of X would indeed have a higher than typical proportion of "gifted" level boys
