Revisiting David Stove's Infamous Essay
Taking a very pedestrian example from current events, consider the dearth of women in physics and engineering. Academia, being what it is, considers this evidence of a vast world-wide conspiracy of invisible men who are diabolically conspiring to keep women from succeeding in the hard sciences. If you're a working academic in one of these fields, you will engage in ritual Maoist witch hunts, looking for sexist oppressors. There is approximately zero evidence for this conspiracy theory, yet it is unquestioned by hard nosed savants who allegedly fear no ghosts. Some of these true believers doubtless understand the concepts of "mean" and "standard deviation," and may even be aware of the fact that men have both a higher mean intelligence, and a much higher standard deviation in intelligence distribution; in particular in the areas of intelligence which pertain to these professions. With these two facts, the conspiracy theory evaporates: there are more male scientists and engineers because there are more males who are capable of doing the work. Virtually nobody is willing to say this, despite it being completely obvious to anyone not equipped with an academic sinecure.
The desire of women for a mate who is more "intelligent" is part of their hypergamous instinct even if some claim that it is not prevalent among American women today. (Some argue that nerds and intellectuals are avoided by women because intelligence is associated with low testosterone/lack of masculinity.) If this desire were to be universal and to be fulfilled, wouldn't we expect the male curve to be skewed towards the right relative to the female curve?
But raw intelligence or "scientific" intelligence may not be identical to what is needed for good practical reasoning, and it seems that is good practical reasoning that is needed first of all in the one who has authority in a household. Differences in the power of the imagination and how it is used may account for some differences in ability (imagining spatial relationships --> sense of direction and geometry, or abstraction + math --> modern physical sciences).
Differences in the structures of male and female brains may be related to differences in the sense powers, and differences in the sense powers may have an impact on our abilities to understand and reason. Some look to abstraction being necessary for thinking about questions of justice; we are aware how emotional attachment can lead to bias or partiality. Is it emotional "attachment" that influences our reasoning (and conversely, emotional detachment that promotes abstract considerations of justice), or is there some other interaction between emotion and reason that can explain sex differences in practical reasoning (if such exist)?
