When doing a presentation one can stick to one’s habits with the desire to be authentic.
However, how the presentation is perceived depends on the audience.
And whenever several people find themselves on stage, their presentation will be perceived within that context. Those presenting can organize themselves by taking turns or sharing the presentation according to their competence. These are techniques that deal with stage time and the content of the presentation. What they don’t consider is the atmosphere. What they don’t consider either is how those on stage are perceived in relationship to one another.
There often will be one presenter who is appreciated more than the other, at least by parts of the audience. A consequence is that all the others will be appreciated less. To use an image, the audience may start to see one of the presenters as the good cop and the other as the bad cop.
That is if they don’t find ways to step together into the zone of appreciation. For example, by establishing a relationship with the audience allowing the audience to feel heard, seen, and welcomed.
Naturally, in some situations, a leader might want to create such an effect. However, it needs to be intentional to serve the presentation.
