From the abstract:

  >We fail to take advantage of the powerful tools of reasoning our best thinkers have discovered over the millennia: logic, critical thinking, probability, correlation and causation, and optimal ways to update beliefs and commit to choices individually and with others.

Key word here being: 'Best thinkers'. Average (intellectually speaking) humans would prefer one-track or one-line thinking. One cannot expect to hold them to higher ideals and deeper thoughts. Above-average humans would (mostly) prefer exploiting average and below-average humans for their personal gain.

Would feel glad to get corrected.
