Klarlund Pedersen

Klarlund Pedersen

Two researchers in Denmark are guilty of scientific dishonesty, the Danish Committees on Scientific Dishonesty (DCSD, Danish acronym UVVU) has concluded.

In July, the DCSD said in a draft report that Bente Klarlund Pedersen had acted in a “scientifically dishonest” and “grossly negligent” manner. She — and many of her defenders — responded by saying that while she had made mistakes, she had not committed misconduct.
