Thanks. I'll have a look at the book.

More generally, I was a little surprised at the pure experimental approach that didn't have a look at the degree of corruption in different real-world societies.

I did mention looking at various subjects in the What>Explore section, one of which will be looking current real world societies.

I focus on experimentation for a few different reasons

1) Experimentation is hard. You can't do it on your own, you need other people, so the most focus goes on it. Otherwise people might just read books and make observations, which leads to the second point.

2) Experiments are a teaching tool. People have to learn that a different way can be better for them and the best way is to try it out for themselves.

3) There are lots of different societal norms and structures we haven't tried, so their might be opportunities to escape our current local optima.

I recommend "From major events like the Enron scandal to low level inefficiency in government, corruption has a massive effect on our day to day lives."

Thanks! I'll change that.

As for the next sentence, I'm not sure whether I don't understand you or don't agree with you. Admittedly, there will be more crime when there are weak barriers to crime, but I also believe that people who want to get away with something will, if they have the power, try to shape organizations which will let them get away with what they want.

I should probably put a qualifying "Most" in front of the people. I was writing it when I was trying to avoid weasel words.

But there is the question of why those you think "evil" get power? Who gets power is also somewhat a societal question.
