Some scientists prefer to occupy scientific meeting space as the proverbial fly on the wall.
Rarely, if ever, comment at the microphone. They are not to be found gesticulating wildly to a small group of peers around the coffee table.
Others loom large. Constantly at the microphone for comment. Glad handing their buddies in every room before and after the session. Buttonholing POs at the slightest opportunity.
Someone just pointed this out to me, so I've been thinking about it.
Obviously nobody wants to end up being seen as a narcissistic blowhard who can't shut up and never has anything useful to say.
But it is good to be known in your field*. And meeting visibility is part of that.
*Cause and effect may not be simple here, I will acknowledge.
