As “open-mindedness” is commonly used, it’s a conflation of three different concepts: inquisitive-mindedness, genuine open-mindedness, and tolerance. Inquisitive-mindedness sounds like what you’re advocating—it’s willingness to consider an idea and accept or reject it, and having rejected it to be less likely to consider again. Genuine open-mindedness is vaguely accepting without critical examination. Tolerance isn’t epistemological, it’s ethical and political—there’s no necessary connection between willingness to accept ideas and letting people do what they want in their personal lives.

What you aft calling genuine open mindedness is what others call credulity.
