Enneagram is a set of nine distinct personality types,
with each number denoting a certain type. To identify an
Enneagram personality, the best option is to use a
questionnaire. However, there are chances of people
projecting a desired type rather than the real one. So
usually, type identification is done with multiple
inputs. In this case, since the cricketers themselves
were busy battling out in the field, the study was
carried through a mix of tools such as looking at
existing literature and background available on the
players, watching videos of their interviews, talking to
their fans and other experts.
Significantly, people are usually born into one and do
not change from one basic personality type to another.
The numerical ranking of the types is also not
significant. So it's not better to be a Nine than a Two
just because nine is a bigger number. While all the
personality types have unique assets and liabilities,
some types are often more desirable than others in a
group.
