• In science: Once we have adopted the usual formula for dipole moment (vector), we cannot choose its direction arbitrarily.
  Further details:
  The standard definition of dipole moment is sum over charges multiplied by their respective radius-vectors. (Mathematics)
  This uniquely determines the dipole direction from the negative centre-of-charge to the positive one. (Physics)
  The opposite direction (sometimes chosen in Chemistry) requires minus before the sum and is thus inconsistent with the standard definition.

• In specific field: The Diatomics-in-molecule (DIM) method for electronic structure calculations is a very useful tool for at least qualitatively correct predictions and interpretations, and its (nonfrequent) significant failures are in most cases due to inconsistent applications.
  Further details:
  One common misunderstanding is associated with claiming the use of the method while doing something quite different (and usually much less accurate). Another, more prosaic origin is when a formally correct DIM-like procedure is used with an inadequate basis set and/or within inappropriate assumptions. The resulting discrepancies certainly cannot be attributed to the method itself.
