Answer:
This information about Jon that he and the others were unaware of would fall under the unknown area in the Johari Window before the incident.
Step-by-step explanation:
The Johari Window is a technique developed by psychologists in 1955. It is commonly used in self-help groups. The Window consists of four areas: open, blind, hidden, and unknown. From a list of adjectives, a subject selects the ones that describe him/herself. Then his/her peers also select adjectives from the list to describe the subject.
In the open area, the adjectives that were selected by the subject as well as the peers are placed. In the blind area, the adjectives selected only by the peers are placed, showing what is perceived by others but not by the subject. In the hidden area, the adjectives selected only by the subject are placed. Finally, in the unknown area, the adjectives that were not selected by any of them are placed.
As we can see, anything that is unaware to the subject or his peers falls under the "unknown" category. However, the subject might very well have those qualities. It's just that he and others haven't seen them being displayed yet. That's precisely what we have in Jon's case. No one knew of his strength, independence, and optimism until he finally displayed those qualities due to an incident. Therefore, they would have fallen under the unknown area before that incident.
