I briefly noted that one reason to respect Arthur Jensen is his high
level of scholarship.
Hal Finney noted that his point
Well, one could respect Einstein without buying into the particular value
of the cosmological constant which he chose. More to the point, one could
respect Einstein's science while deprecating his pacifism (or
vice-versa). I think Flynn, because of his politics, sees the race issue
as a social construction rather than a testable hypothesis. SO, yes, you
are exactly right. Flynn uses science in so far as it reduces the case of
those whom he opposes politically, but ultimately, because he is a
socialist rather than an objectivist, he holds the racial issue as
unassailable. Yes, he is inconsistent, and i think that this
inconsistency will grow rather than diminish as the evidence

Regarding the meaning of score inflation I noted that:

Agreed. This is the central issue in modern intelligence research: grounding intelligence in a theory rather than in it measure. many people act as if the "quote" from Boring was true: that intelligence is what the tests measure. I put quote in quote marks as he did not in face say that.
If so, it would be like physicists regarding the trials in a Wilson cloud chamber as BEING the sub atomic particles they study.
Work to elucidate the effect is underway in several laboratories around the world.

You are right. from the point of view of science, we are seeking to carve
nature at here joints: thus intelligence will be whatever is most able to
explain the data. Intelligence may even disappear as a scientific
construct if it is found to have an internal structure.
All of this is, as you note, irrelevant for society (well, not irrelevant) but supervenient perhaps. What matters is whether we are increasing the rate of construction of space ships or decreasing it. My own belief is that most of the variance in this is driven by demographics. After a period of gross torpor beginning in the 1920s and reaching a nadir in the 70s, we are now on an upswing that is largely driven by demographic variables such as large numbers of 20 and 30 something kids all competing with each other by building the smartest new extension to Linux or way to insert new information into the genome: we 'ain't seen nothing yet.

When was the last time that a socialist ever saw a renaissance ;-)
Like Jim Watson said: "some people just always pick the wrong answer." DNA? Nah, that 'll never work ;-)
