Who ever heard of a conference without evaluations?

I spoke recently at a conference where the organizers didn’t seek real audience feedback.  

For reasons that escape me, they didn’t ask the attendees to rate the speakers on a simple multiple-choice 1-5 (or 1-10 or whatever) basis.

I like those, because it’s easy for the audience to fill out quickly and provides relatively objective comparative data. Sure there are often outliers who, for personal reasons, over- or under-evaluate a speaker.  But it provides a good overall sense of how you did. 

Then the Comments section offers additional subjective context for the scores.

But this conference only sought narrative, subjective Comments. The obvious and predictable result? VERY few people responded, which means there’s very little useful information for the speakers to use to improve their presentations.
