Alternative title: introverts’ helpless inability to communicate their uniqueness.
All people are unique (although that according to Monty Python: “all the others may be different, but I am not”). Extroverts, however, seem to exhibit their uniqueness a bit more effectively than the introverts. The way modern societies are built, especially in the western world, benefit people who stand out in workplace, education, as well as in every social interaction.
In an environment where there are countless units – individuals offered for communication; the pace is getting faster; communication is getting wider but not deeper; there is information overload and obviously increased competition, the only way to communicate effectively is to just stand out. Extroverts can do it better as it is their natural attitude to find energy and thrive in busy, interactive and team environments.
Conversely to what it used to be in the past, nowadays, there is not the time for an introvert to be “discovered”. Besides, it tends almost to be shameful for someone to be an introvert or it can even be regarded as a weakness. Nevertheless, researches show that there is no positive correlation between extraversion and work performance generally, apart from specific areas such as sales (but the same applies for the introverts in other fields).
