Mallory Harris is critiquing Dr. Levitt because he has made scientifically incorrect statements and when presented with the contrary evidence has not corrected his misstatements. The article documents these misstatements, implores him to correct the record, and he does not. These misstatements are clearly presented and cited. It would be problematic for a medical doctor to disseminate medically incorrect information to the public and not correct or clarify it. Similarly, it is problematic for a scientist to disseminate scientifically incorrect information and not correct or clarify it. It would be a simple thing for him to simply tweet, "On x date I tweeted y. The evidence now suggests that this statement was incorrect." The science on this continues to evolve, acknowledging that sometimes we are wrong is not a stain on one's reputation. It is the mark of a scientist who is pursuing evidence rather than a narrative. Dr. Levitt is pursuing narrative over evidence, and his actions have consequences.
