What if I fail?

Parking the car in a multi-story I noticed this sign through the window of a building opposite.

It got me thinking about what a personality test is meant for?

Although never having taken one, perhaps I should, maybe there is perhaps some deep and meaningful answer that can be obtained by answering questions about whether you strongly agree, agree, disagree or strongly disagree with a statement.

It's not like you can fail it, can you?
