Nonsense. Open minded means not precluding possibilities based on irrational bias, which would only increases intelligence.

Sure, if the biases are actually irrational, but in this case the biases are things like "idk maybe we should follow the scientific method", while Loeb pushes "here's an idea that is unfalsifiable and untestable, but look its peer reviewed and its on a harvard domain name so you have to pay attention to me".

Loeb is, to be very clear: unintelligent and unscientific. He has no desire to actually test the theories he publishes, and because of that, most of the theories are literally untestable. He just wants to shit-publish wild ideas, which is totally fine, if we were talking about a blog or something of that similar caliber. But that would not attract the $$$ views he demands to afford his lifestyle.
