If you’re having a communal event anyway, maybe it makes sense to watch a video together (movie, TED talk, debate, whatever), pause it every few minutes and make predictions about what happens in the rest of the video. Focus on short-term predictions like “in the next two minutes...” so you get even quicker results.
You get a tight feedback loop and several rounds of it. That allows you to actually try different strategies and see how they fare.

I imagine it would also be quite fun.
