Users' minds take shortcuts to get through the day. Usually they’re harmless. Even helpful. But what happens when they’re not? In this talk I’ll use real-world examples to identify some particularly nasty biases that frequently lead users to make bad decisions. I'll then talk about some content strategy and design choices we can use in our apps, designs, and platforms to redirect or eliminate the impact of those biases. Finally, I'll explore our own biases as designers and some methods to prevent our own blind spots from hurting users.
