How many draws would it take to show an edge from bending?

You should probably do two disproportionate batches for the test.

Why?
It's not whether you win or lose; it's whether or not you had a good bet.

I would think you need to involve a kid or other person who doesn't know the theory, so you get an unbiased draw. Kind of an offer a hatful of tickets with various proportions of bent/straight, and have them do 10 straight draws. Even a little misdirection where you write down the ticket numbers or something just to see what different people grasp without knowing what you're testing for.

I thought I would get several different people to pull the tickets to see if there is a correlation. My three kids can be among them. I need people who won't over-think it.

You have to have some sort of experiment control group but I don't know how to pull that part off. You would want to test them at an advantage already and at a disadvantage to test the effectiveness or possible lack of.

The results of the control group are known. If nothing is bent, they are all equally likely to be picked. This doesn't need to be verified experimentally.

The question is, if some are bent, are the bent ones more likely to be picked?

I think we tested this a long time ago. There is no doubt crimping and bending works better. How much better is the real question.Bending is good if it keeps the bend and does not flatten out with the weight from other tickets, not all tickets are the same. As i said before you should do half and half, just in case they avoid the bent ones on purpose.

Maybe I'm not the sharpest tool in the shed, but I still am having a hard time understanding your suggestion. Feel free to use plain simple English. I thought one used control groups for such things as testing medicines, where a placebo effect may be at play.

What I'm thinking of doing is folding half and not folding the other half. Of the folded half I am not sure how to fold them. Maybe just a fold down the middle, maybe a double fold, maybe rolling, maybe some combination. Personally, with real drawing tickets I just fold mine half way at a 90-degree angle.

What do you mean by crimping? Just turning a corner up? I've seen all sorts of tickets (bent all sorts of different ways) in the barrel. When they picked them I tried to get a look at the tickets and they did not seem bent (although I was a bit far away) which lead me to ask this question. As you say, it's possible that they are avoiding the bent ones. Then again, it wasn't the same person who picked each ticket.
