Cognitive psychology for UX: how to avoid the false consensus effect

We all see the world through our own unique filters. These filters are based on our personal experience, culture, context/environment, and our frame of mind. And they come with an unintended side effect that most of us aren’t aware of: they cause us to falsely believe that other people see the world the same way we do.

Human beings have a natural tendency to overestimate the degree to which other people will agree with us, think like us, and behave like us.

It’s your job to protect your team from falling victim to this bias.

Keep your focus on the users. And be rigorous about identifying and challenging the assumptions your team is making about who they are and what they need.
