The last EAG I attended had rules restricting handing out materials.
Having just finished watching this Dwarkesh video which explained how big a deal pamphlets were when they were first invented, I'd actually go the other way and encourage it instead.
Here's my reasoning: Talks have been de-emphasised in favour of one-on-ones at EAGs. There's a lot to like about one-on-ones, but one disadvantage is that we've removed a key avenue for ideas to gain a critical mass and enter the water supply. Pamphlets could fill this gap. After all, if you see a good pamphlet, it'd be quite natural for it to come out during a conversation and for you to pull it out.
Additionally, when you have dozens of one-on-ones, things often blur together. Now, you can be disciplined and keep notes, but that's hard and often I find my phone is short of battery. If people handed out pamphlets containing their proposals or takes, then it'd be easier to review them afterwards; conversations would be much more likely to have effects that last. Two further benefits: it might be more efficient to exchange pamphlets at the start of a one-on-one and producing a pamphlet would convince people to figure figure out how to communicate their ideas clearly.
