One obvious example is decolonization, which killed more people than the nazis. No postcolonial government was as good as the colonial government it replaced. Even the very worst colonial governments, for example the Congo, were followed by even worse postcolonial governments. In some cases, such as India, they very slowly got better over time. In other cases, like the Congo, they just keep on getting worse with no bottom in sight. They are back to eating each other in the Congo - of course they were back to eating each other as soon as the whites abandoned them, but the number of people being eaten is increasing.
Decolonization denial is arguably worse than holocaust denial - it killed more people, and continues to kill more people, but decolonization denial is mandatory, while holocaust denial is forbidden.
Here is a view of decolonization you will not get from Harvard
Then there is evolutionary psychology, which tells us that Archie Bunker was right about nearly everything,
For a thousand years before the mid nineteenth century, pretty much everyone agreed that equality between husbands and wives would destroy marriage and fatherhood. Then in the nineteenth century, they introduced marital equality. Observe the result.
There's been a lot of discussion in this thread about whether or not your examples are valid. But there seems to be a more substantial problem: Your primary example, of whether or not decolonization was a good thing or was handled well is extensively discussed in academia. Similarly, most of the people doing ev psych are tenured professors and the like. So whether or not the views expressed are accurate, the claim that they are ignored by academia seems to be false.
Now, moving on from that, let's look at your claims.

SIAI benefactor and VC Peter Thiel has an excellent article at National Review about the stagnating progress of science and technology, which he attributes to poorly-grounded political opposition, widespread scientific illiteracy, and overspecialized, insular scientific fields. He warns that this stagnation will undermine the growth that past policies have relied on.
