Definition of Selected Instances:
Support is drawn for a position by choosing only those cases or instances which back it up and disregarding those cases or instances which either contradict or do not support the position. The form of the argument is: All B is C; because B1, B2, B3, and B4 are C. The form is invalid; the disputer knows that at least B5 is not C.

Someone says, 'All professors are conceited.' When asked for his evidence he replies, 'Well, how about Professor Smith, and Professor Jones, and Professor Blaine. Everybody knows they're as conceited as they come.' But he deliberately skips over Professor Blake whom he knows to be a model of humility.
