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.

What if stuff that wasn’t confirmed was harder to read?
Daniel Craig’s final outing as 007 has finally been named with the appropriately titled No
Time to Die. The announcement came Tuesday with a short video teaser that showed
Craig’s dapper James Bond taking a short stroll, and then the title reveal.
It is rumored that the film’s previous director, Danny Boyle, left the project because he
wanted to kill off James Bond in the end, a decision that Eon wouldn’t stand for.

We must rapidly begin the shift from a ‘thing-oriented’
society to a ‘person-oriented’ society. When machines and
computers, profit motives and property rights are considered
more important than people, the giant triplets of racism,
materialism, and militarism are incapable of being
conquered.
