Cherrypicking

Cherrypicking is a dishonest debate tactic that involves citing evidence from a particular source that supports an argument while conveniently ignoring other evidence from the same source that refutes the argument.

Quote mining is a variation that involves selectively quoting one source to make it seem like it means something other than its actual meaning. This usually involves quoting a scientist or other expert stating a problem but leaving out the speaker's statement of the solution to that problem.
