Rather, scientists are wrong.

Terribly often, science grinds to a dead halt on some range of subject matter until certain scientists retire or die. It is easy to list remarkably recent cases where they did finally die and work could proceed, and many others where they have not died yet and the field is still stuck fast.

Science will always be incomplete. It has nothing to say yet about most possible questions. What it does pronounce upon should be reliably correct, but that is often not true, traceably to those individuals who maintain falsehoods. Sometimes the falsehoods become doctrine and hang on even after the offenders have obliged by dying.
