As is the case with all generalizations, this one is simply not true. Are there programmers who are introverts? Will you find there are software developers who prefer to work in an office with a smaller group of people? Do programmers hate speaking in bigger meetings?

Sure, like in any other group of people, there will be some who are introverted and some who are extroverted, so we would not apply this subheading specifically to the IT department of the company.
And besides personal preferences, especially in the times of remote and hybrid working, collaboration and (over)communication are absolutely essential.
Apart from these myths, you can read more about skills that programmers need to nurture constantly in another blog post.
