One of the reason is that it can be anxiety-provoking to put one self in a situation where oneself is evaluated by others. Speaking in front of a group can create feelings of vulnerability and fear dged or rejected.
Another reason is that peole may have negative experience in the past when speaking in the public. If someone has a bad experience in the past such as being laughed at when speaking it can make them hesitate when trying to speak in the public.
Many people fear talking to strangers or speaking in front of a group of people due to a condition called social anxiety disorder (SAD). Social anxiety disorder is a mental health condition characterized by intense anxiety or fear of social interactions and situations. These fears can be specific, such as fear of speaking in public or fear of meeting new people, or they can be more general, such as fear of being judged or evaluated by others.
Some of the common symptoms of SAD include:
The exact cause of SAD is not entirely understood, but it is believed to be a combination of genetic, environmental, and psychological factors. People with SAD may have an overactive amygdala, a part of the brain that processes emotions and is responsible for the fight or flight response, which can make them more susceptible to anxiety.
Additionally, people with SAD may have learned to associate certain social situations with negative experiences, or have experienced negative or traumatic events in the past that have contributed to their fear.
SAD is a treatable condition, and there are a variety of effective treatments available, including therapy, medication, and self-help techniques. It's important for people who experience fear of talking to strangers or speaking in public to seek professional help, as it can greatly impact their daily life and prevent them from reaching their full potential.
