Jung did a lot of great work in analyzing personality types and this application takes his teachings and uses them to create a profile of someone.
Determining someone's personality is a very quick four-step process based around ticking a series of check boxes that best describe the user.
Once you've entered the information, the app provides a fairly detailed breakdown of the person's make-up and particular environments that they would thrive in.
On paper, this might sound like a very good way of profiling someone, say, for instance, for a job interview. However, the test itself leaves a lot to be desired.
For starters, you're asked to tick five attributes that best describe you from a list of only around ten. This means that you end up having to compromise and tick boxes that don't really apply to your subject, skewing the test somewhat.
Some of these attributes are also pretty vague (I don't recall Jung ever assessing someone's 'perspiration'). As a result, it makes you question the validity of the test results.
