In many instances, attractiveness is tantamount to having social skills. It's not even a matter of developing a more sophisticated skillset; attractive people (and all the people who are subject to affinity bias) are just given the benefit-of-the-doubt more, and more consistently. This is where advice like, "Be yourself," and, "Don't fear rejection," and the idea that, "the only thing stopping someone from connection is their willingness to dare to try," come from: people whose attractiveness has preempted the requirement to really change or consider how they approach interactions.
