The data relies on the use of vocabulary so it is critically important to know the vocabulary they are using to test. I would hope such a vocabulary would include words from many different disciplines. The point is that deciding which is the proper vocabulary to test may in fact decide the outcomes. Persons who are literary academics are going to have a very different vocabulary than persons who are scientists. It may be that the vocabulary being tested for is quite simple, middle school level, and therefore includes words that are deemed part of all disciplines.Yet, observably, we are.Phenotypic variation is a thing, but statistically we're not moving toward greater intelligence.
So we must conclude that your analysis is flawed (or that something has changed radically, on a timescale FAR too short for evolution to be relevant at all).
Observation ALWAYS trumps theory.
We're accumulating knowledge, and in that way we're becoming collectively smarter, but cognitively we're not. The only statistical evidence I've seen mentioned that, genetically, we're becoming less intelligent as a whole. This isn't a hill I'm willing to die on, and I'm happy to be proven wrong, but here's an example of data:
Interestingly I was a Literature major in college. As such, and because most freshmen detest having to take Lit classes as part of a core curriculum, many persons would ask me to have a look at their work before submission. Some of those efforts were dismal and some were quite adequate imho. My point is that I wasn't examining work destined for Calculus for Physics or Computer programming. No students were required to complete credits in those areas as part of their requirements though those classes would have satisfied certain more basic requirements.
And the effect of those vocabulary scores was estimated in I.Q. changes over time. Not sure how to process that. Was I.Q. not tested? The estimated I.Q changes were less than one point over many years. The little I know about statistics and "statistically significant" differences tells me there is a lot more information to be gleaned. I'm reminded of my years in manufacturing where persons would proclaim in meetings that this or that changed from last month or last quarter and would never calculate averages over time to see if anything really did change or was trending because they had no statistical training.
One thing is certain in my life, and that is that falling love was not a rational exercise. Getting married and having children was definitely a rational undertaking because those things consume resources unlike falling in love.
