Speaking of the effect in the brain, a rare but real side effect in many people is anxiety to the point where they have to discontinue the med. I wonder why.
As this is psychology, the goal is not always to believe the exact truth, or to dwell on things that have lower probability of happening, as it does not give the individual in question any advantage, it just causes them to become overly afraid and unable to protect themselves.
Everyone has a different take on story points, but the original idea was for them to record _effort_, not value.. more story points are actually worse. Delivered value is better. So digging a ditch and filling it in would get a bunch of story points but have zero value.
But managers want to look at the numbers they have, which is story points.
