  In the last two decades, the field of neutrino physics has made enormous
progress in measuring the strength and frequency of neutrino and antineutrino
oscillations. Along the way, there have been many instances of misunderstanding
which led to wrong measurements or speculation for new features of neutrino
physics that are not now accepted as correct. This is part of the natural
process of science, but given the well-accepted notion that we learn from our
mistakes, it is worthwhile to look at some examples and see what the lessons
might be. With that goal in mind, I have a list of results which might be
termed neutrino mistakes, with the fact in mind that there is no well-accepted
definition of a mistake, and no unique threshold for counting something as a
mistake when you change your mind after you obtain more information. After
making the list, I chose seven of them to discuss. No clear conclusions were
drawn from this exercise, but some interesting issues regarding putative wrong
results are discussed.
