I think this is 100% correct, and very surprised the author of the article and/or study didn’t figure this out.

Here’s how you could (possibly) prove that.

Instead of the options being you get the money or not, the options become you win you pocket the money, you lose the money goes to a charity of your choice.

I think 100% the person would always choose the outcome with more money, regardless of the level of trust with the person giving the experiment.

That is, you completely remove trust from the equation.
