There's no need to apologize. This whole line of work by Haidt and his associates has been heavily attacked on the grounds of poor methodologies, and Haidt's responses were astoundingly bad. For example, someone spot checked some of the hundreds of studies he presented and found none of them really supported the social media/teen girl mental health link he was asserting; his response was "they can't all be wrong" and "you shouldn't demand a high standard of evidence in a crisis" (where the evidence there was a crisis was the same evidence he was presenting...)
