"In this study, we use a large-scale incentivized experiment with nearly 1,300 participants to show that the gender gap in spatial abilities, measured by time to solve a puzzle, disappears when we move from a patrilineal society to an adjoining matrilineal society."
It is presently a commonplace of Western culture that women are worse at spatial reasoning than men, and this is commonly attributed to intrinsic biological differences.
It turns out this may be highly questionable. A study in PNAS studied two nearby tribes in northeast India, one with a strongly patriarchal organisation, one with a strongly matriarchal organisation. Both share the same agrarian diet and lifestyle and DNA tests indicate they are closely related.
In the patriarchal society, women did noticeably worse on spatial reasoning. In the matriarchal society, women and men did about the same.
The authors carefully do not overstate their results, claiming only that they demonstrated that culture influences spatial performance "in the task that we study." However, this promisingly suggests quite a bit of room for improvement of measurable aspects of intelligence may be feasible with proper attention to culture and nurture.
What measurable aspects of intelligence do you attribute to genetic causes? Can you test it this well? How would you fix it and help people be all they can be?

I chose the example of the Soviet Union because now, since 1990, academics can speak the truth on the Soviet Union. But their failure to speak that truth before 1990 implies that on one thousand other issues, they cannot speak the truth, which should undermine your confidence in your position.
And since, on an issue where the truth is now permitted, the evidence is that academia was previously totally unreliable to the point of being entirely worthless, you would like to keep the issue to topics where the truth is, for the most part, still not permitted.
But your example was incomplete. Your example of a "massive flagrant barefaced lie" was a forecast from 1961 of the projected growth of the USSR's real GNP versus the US's real GNP between the years of 1960 and 2000. You said of such claims that "doubting these lies would cause a student to be swiftly failed". Do you in fact have an example of a student who was failed specifically for doubting that forecast from your link?
(For reference, here is the 1961 forecast from the Samuelson tex... (read more)
