To my limited knowledge, there are remarkably few proposed psychological
adaptions proposed for humans. I have proposed 4 of them (one of which was
informally proposed by Tooby about 1980) where the logic of how they would
have been selected in the ancestral environment seems very good if not

I am not sure what you mean here. Could you explain?
Traits like the ability to capture-bond and the modes of going to war are
and always were of conditional utility. They are not normally invoked
unless you get captured, your group gets attacked, or your group gets into
a situation where the risk of war seem better than
High drive to do things in the pursuit of status has become partly
decoupled (due to birth control) from its original function of
promoting reproductive success but that is *very* recent.

"Spandrels" are known as "byproducts" in EP speak.

That's a point I have argued for at least ten years:
"This is very speculative, but "religious" memes could have "functions"
such as reducing the effects of grief or answering philosophical questions
about which it was (genetically) unprofitable to ponder. These memes would
be favored in a causal loop if they improve the survival of people carrying
genes which tend to destabilize a person's mental state, but otherwise
improve their survival.
"Such genes might (for example) contribute to intelligence, sensitivity,
and forming strong emotional attachments. After a few millennia, religious
memes and conditionally advantageous genes would become quite dependent on
each other. In an environment saturated with religious memes, there would
be little pressure for minds to evolve that could get by without
Thus "smartness" which Calvin make the case for being a byproduct of
projectile hunting, opens a niche or religious memes, which contribute
(perhaps) to the survival of certain genes. Definitely a cases of genes and memes feeding into each other's survival--as you would expect.

For the two I discussed in detail in the "Sex Drugs and Cults" paper, it
looks more like the mechanisms were there from tribal days, long, long
before memes such as Islam or scientology used these mechanisms to spread
across the world.

The other group (transhumanists) this was directed toward is very
interested in upgrading humans.
To a very high degree we do this today under the name of "education" and
information locating tools.

If people had knowledge of their evolved in psychological traits, *perhaps*
they could be more resistant to being manipulated. A certain person just
got his output shunted off the mailing list. Wouldn't it be better if
people understood more about how to present various memes in a style that
did not offend people?

No, scientology was originally concerned with bleeding members for the
maximum amount of money they could get out of them. When he was alive
Hubbard skimmed a million a week. Nowadays the money is mostly used in an
attempt to prevent bad PR about the group from reaching potential
customers--a hopeless task in the face of the Internet, but the current
leadership people are as hung up on what Hubbard said as the customers so
they can't change.
