Why is it a good idea to disclose a bit about yourself when speaking to groups?

To improve connection with your audience and create empathy.

Explanation:

When you disclose a little bit about yourself, your audience is able to see you as a normal person and they will be able to relate themselves to you (empathy).

Usually you should try to share information about both your faults and strengths, and not just only your outstanding capabilities which will make your audience dislike you.
