What makes a museum historically responsible?

Are there museums that visitors should avoid because their history is unreliable?

Ordinary mistakes do not disqualify a museum, but deliberate distortion for profit or politics turns it into a history-themed attraction rather than a responsible museum.

Asked which museums visitors should avoid, the answer declines to issue a public blacklist. Most museums are good-faith institutions even when labels or displays contain errors, and those mistakes can often be corrected. The dividing line is purpose: an organization that deliberately misrepresents history to make money or serve a political audience has abandoned the museum's educational responsibility. Such a place is a history-themed amusement park rather than a museum. This standard separates imperfect scholarship from intentional distortion.
