Self-censorship may play a greater role in suppressing scientific research than laws or regulations, according to a new study.
What scientists can and cannot do is, to an extent, officially dictated. For example, human cloning and embryonic stem cell creation have been restricted or banned by some governments.
But the new study suggests that such regulations pale in comparison to informal constraints—the possibility that findings could provoke moral outrage, for example.
"What we found is that researchers are very aware of controversy and decide what to study ... in relation to what they think is appropriate," said Joanna Kempner, a sociologist at the University of Michigan in Ann Arbor. "It's these silent rules that really guide what researchers do."
