Unless you work on a station where your job is to be an authority (news stations or a highly specialized format or show), there’s no need to validate your credentials every time you open the mic. Yet personalities burn huge amounts of airtime trying to justify why they are talking about a story. You’ve heard it. The qualifiers, disclaimers, and endless, usually unnecessary background. It is defensive broadcasting. You don’t have to establish credibility to be entertaining, so stop trying to be an expert.
Listeners are not grading you on expertise. They are judging you on your ability to hold their attention and engage them. The vast majority of performers are entertainers, and audiences simply want to feel something. That should shape how you select, frame, and perform every story.
