Why are humans wired to be afraid of public speaking?

The fear of public speaking, known as glossophobia, is a common phenomenon and can be attributed to various factors rooted in human psychology and evolution. Here are some reasons why humans may be wired to feel anxious about public speaking:

1. Social Evaluation:

   • Humans are inherently social beings, and the fear of public speaking often stems from the fear of social evaluation. When speaking in front of a group, individuals may worry about how they will be perceived, judged, or evaluated by others.

2. Evolutionary Factors:

   • In ancestral environments, being the center of attention or speaking in front of a group may have signaled a potential threat. Humans evolved in small social groups where rejection from the community could have had survival implications. Consequently, the fear of public speaking may be a vestige of our evolutionary past.

3. Fear of Rejection:

   • The fear of public speaking is closely linked to the fear of rejection or social exclusion. Humans have an innate need for social acceptance and fear being ostracized by the group.

4. Performance Anxiety:

   • Public speaking often involves being in the spotlight and performing in a way that others can observe. Performance anxiety can trigger the body's stress response, including the release of adrenaline, leading to symptoms like nervousness, shaky hands, or a racing heart.

5. Fear of Mistakes or Failure:

   • Humans are wired to avoid making mistakes, as errors in communication or performance could be perceived as a sign of incompetence or weakness. The fear of making mistakes or failing in public can contribute to anxiety.

6. Lack of Familiarity:

   • Speaking in public can be an unfamiliar and novel experience for many individuals. The fear may arise from the uncertainty of the situation and the fear of the unknown.

7. Social Comparison:

   • Humans have a tendency to compare themselves to others. When speaking in public, individuals may worry about how they measure up to others, leading to feelings of inadequacy or self-doubt.

8. Cognitive Biases:

   • Cognitive biases, such as the spotlight effect (the belief that others are paying more attention to us than they actually are) and the imposter syndrome (feeling like a fraud despite evidence of competence), can contribute to public speaking anxiety.

9. Conditioning and Past Experiences:

   • Negative past experiences, such as a humiliating or embarrassing moment while speaking in public, can contribute to the development of a fear of public speaking. Individuals may carry these negative associations into future speaking situations.

While the fear of public speaking is a common experience, it is not insurmountable. Many individuals successfully overcome public speaking anxiety through education, practice, and therapeutic interventions. Techniques such as cognitive-behavioral therapy (CBT), exposure therapy, and mindfulness can be effective in addressing the underlying fears and building confidence in public speaking situations.
