Humans are forgetful creatures. We forget our keys, we forget where we parked our cars . . . and, importantly, we forget our training. According to German psychologist Hermann Ebbinghaus, after two days humans will forget 75 percent of the information they’ve learned. What’s worse, research from the University of Waterloo shows that after a month, only 2 to 3 percent of information will be retained. To add to the challenge, the workforce is getting younger; and as ages drop, so do attention spans. Studies have shown that Millennials, on average, have an attention span of about 12 seconds, and their younger counterparts, Gen-Z, can concentrate completely for about eight. For the most part, these individuals would like guidance when they come across problems at work. This means many companies are looking into AI to provide on-demand guidance when and where it’s needed, rather than investing in traditional training methods that are likely to be forgotten anyway.
