Next to biases, the closest thing to a silver bullet a marketer can have is a profound understanding of self-interest.

If you understand what makes us make all the little selfish decisions that we ignore every day of our lives, you can find a way to get your product into the hearts and minds of your users.

Always be on the lookout for biases. Whether it is yours, your users or your societies. People feed on biases and they will devote vast blocks of their time to things that feed into them. This is probably some of the best and saddest information marketing advice I can give you.
