Robert Pollack quotes:

The freedom to make and admit mistakes is at the core of the scientific process. If we are asked to forswear error, or worse, to say that error means fraud, then we cannot function as scientists.

My morale has never been higher than since I stopped asking for grants to keep my lab going.

Science differs from politics or religion, in precisely this one discipline: we agree in advance to simply reject our own findings when they have been shown to be in error.
