Science Education is No Guarantee of Skepticism

These results are consistent with the notion that having a strong scientific knowledge base is not enough to insulate a person against irrational beliefs. Students who scored well on these tests were no more or less skeptical of pseudoscientific claims than students who scored very poorly. Apparently, the students were not able to apply their scientific knowledge to evaluate these pseudoscientific claims. We suggest that this inability stems in part from the way that science is traditionally presented to students: Students are taught what to think but not how to think.
