We should govern our actions by assuming that people are more good than bad. Whereas, most of our social policies dictate that people are more bad than good. That you know if you do something, it'll be seized by the rich to exploit the poor.
Audiences are savvy. You can never go wrong assuming the best of them.
Assume that people are good until you actually and specifically learn differently. And even then, know that they have potential for change and that you can help them out.
The presumption of innocence is not just a legal concept. In commonplace terms, it rests on that generosity of spirit which assumes the best, not the worst, of the stranger.
If we assume the best in people, we can radically redesign our democracy and welfare states.
I'm a big believer you should design work around a vast majority of people who want to do the right thing rather than around the tiny minority who might take advantage.
Assume the best intent in others around you. You will often be right, and even when you're not, people can rise to your view of them. Not always, but enough that I believe it's worth it.
I think audiences deserve the benefit of the doubt. I prefer to be surprised by them rather then just assume they'll react negatively to any new idea.
