Joshua Porter quotes Neil Gaiman:
“When people tell you something’s wrong or doesn’t work for them, they are almost always right. When they tell you exactly what they think is wrong and how to fix it, they are almost always wrong.”
Wise words and an important prinicple in user research (or any research, for that matter). User feedback should always lead to careful consideration where a problem has its roots, not to haphazard quickfixes just to satisfy that one user who we happened to ask or who is the most vocal. As Porter writes:
in the end we should definitely listen to users, but only to self report their experience and not to do our jobs for us.
