We quickly forget what we’ve learned

Like first year college students who forget 60% of what they learn in high school, studying merely to get the CPE credit suggests that employees, too, will quickly forget what they learn.

German psychologist Hermann Ebbinghaus pioneered experimental studies of memory in the late 19th Century, culminating with his discovery of "The Forgetting Curve."

He found that if new information isn’t applied, we’ll forget about 75% of it after just six days.
