Science writer Bethany Brookshire agrees.

It was super intimidating to me. The only thing that gives me courage now is a press badge. ☺️

I know exactly what my colleagues are talking about: little knots of people with grey hair talking to each other, and not to the poster presenters. The age differences make it clear who are students and who are the senior scientists.

The “zone of intimidation” is probably more common and more obvious at big conferences, because there is ample space between posters for people to mingle. Big conferences are more likely to have attract people who go there every year, so there is greater chances for people to establish annual “conference cliques.”

While that hallway conversations are the best part of conferences, it can be poor form on the part of conference veterans to interact mostly with each other. Some say they plan on being in the “zone of intimidation”:

Visit posters from labs you like, introduce yourself. Many PIs will be lurking nearby (including myself) and would be happy to chat briefly then.

Why “lurk” in the PIZI? And why tweet that you can talk “briefly”? Why not talk extensively to students and earlier career colleagues? The organizers of the Keystone Antimicrobial resistance meeting sent this to their participants:

Please attend the poster sessions and interact with junior colleagues. You are the reason the rest of the attendees were attracted to the meeting. Please mingle and inspire the next generation of researchers, clinicians, and policy makers to remain engaged in this amazing important topic.

Yes, talk to your colleagues, but try to not have your full academic reunions (“It’s been so long! How’s your partner and kids? Are you still at...”) in the poster session. Get a phone number, send a text, and meet for dinner.

Another possible solution to that senior people should present a poster of their own. (This is a variation on my belief that senior scientists should have a project of their own.) Get in there in the trenches and remember what it is like to try to attract an audience and talk about the project for hours at a time. Posters should not be the sole domain of first time conference attendees.
