Indeed; do love your blog :). Thank you for reminding me of that post - I was about to spend an hour writing a frustrating post of my own about how people shouldn't base decisions on how *they* think a mass of other people would feel. This has precluded that ;p.
The actual phenomenon is called the Typical Mind Fallacy:

It's why nerd-designed interfaces are so LEGENDARILY AWFUL, and why engineers are reliably shocked when they see what actual (not theoretical) users do when put in front of their stuff.
Generalising from one example is better than generalising from no examples ... but not better than doing actual usability testing.
