Instead he told us to leave the studio and GO WATCH PEOPLE. Watch ppl do whatever it was our design was supposed to make better.
Even the best imaginations are ego prone. Are you designing for yourself or to solve a problem for someone? If it's the later, how can you NOT start by observing 1st?
That's where big insight's come from. It's cheap and potent and transformative. User researchers know this. They'll help you.
"Have u ever watched an actual person try to do this?"
Or at least watched someone try to do something similar. Or at bare minimum watched dozens of ppl in usability labs over years.
It's just a PM or Exec talking about a great sounding design idea. Followed by the "highlight reel" of people actually trying to use it and utterly failing.
Our industry relearns the same dumb lessons over & over. We don't have to, but ego is in the way.
