The danger is not only that politicians and private institutions with axes to grind will find tame or corruptible social scientists to support their positions. The greater danger which recent experiences both here and abroad, e. g., Lysenkoism in Russia, have revealed is that partisans primarily political in interest and intention either accidentally or deliberately infiltrate the ranks of science. In the case of the Lysenko episode, and comparable events in Nazi Germany, the disturbing realization to scientists was that the exile or death of those ejected from their academic positions followed what seemed initially to be severe technical criticism by fellow scientists, but was actually politically staged.
