The core trait of a scientific mind is that when its commitments clash with evidence, evidence rules. On that count, what grade do liberals deserve? Fail, given their reaction to the latest evidence on universal health care, global warming, and universal preschool.When the facts contradict your expectations, believe the facts.

Ellwood, the Kennedy School dean, said in a statement that any views and conclusions by its graduates do not reflect the views of Harvard. He urged scholars and critics to engage in reasoned discussion and criticism after fully reviewing the work.
