Intimate Connections: The Clinically Proven Program for Making Close Friends and Finding a Loving Partner by David Burns: A copyrighted version of cognitive therapy, that has been useful to some members of the incel mailing list. Author does not fully understand involuntary celibacy, and he oversimplifies other stuff, but that's normal for a book. Worth a look.

Social Phobia

Social phobia is a psychiatric diagnosis (classed as an anxiety disorder) which applies to some shy people, and can include dating anxiety. Avoidant personality disorder, agoraphobia and Aspergers Syndrome are related diagnoses.

Dying of Embarassment: Help for Social Anxiety & Phobia by Markway et al: An excellent primer on the social phobia diagnosis. Mentions dating but does not acknowledge the complexities of becoming and being incel. Includes a treatment program: paced breathing, cognitive therapy, a hierarchy of exposures. Medications are also discussed.

Social Phobia by John Marshall: Another great book, for laypeople and clinicians alike. Explains the social phobia diagnosis, explores possible genetic origins, and compares it to other anxiety disorders. Makes a great point about Alcoholics Anonymous: if you drink to self-medicate your social phobia, you probably can't go sober to an AA meeting and stand up in front of the group! Also points out that dating behaviours such as "the copulatory gaze" are difficult for social phobics.

Sexpectations: Women Talk Candidly About Sex And Dating, by R. Louis. "The author interviews a series of women to find out what they think about men, how they like to be approached, and what they think about sex. The ladies liked confidence, but not cockiness. They do like to be treated nicely ( i.e. sincere, good listener, honest ), but not if it is done out of desperation. That is the paradox of success with women, according to the author. They do like courting, flirting, being approached, et cetera, again as long as it is not done in a cocky way."

Overkill : Mass Murder and Serial Killing Exposed by Alan James Fox, Jack Levin, James Alan Fox. (This is relevant because the media often highlight the celibacy or loneliness of multiple murderers.) A quote from the book: "the typical serial killer is intelligent, socially and sexually competent, a first- or second-born child, and a skilled worker. He lives with a partner, is mobile, drives a relatively new car, and follows his crime in the media. Contrary to popular mythology, he is not a nomad or a recluse and hardly ever uses a firearm."
