Is Type A personality and being an alpha (male) the same thing?
There's a lot of overlap between the two's personality types but not quite the same.  Type A personality is genderless and refers to someone generally meticulous on details and likes to take charge.
Alpha male is a term that was misunderstood and later overturned based on pack behaviors of wolves.  The researcher who coined the term 'alpha' as a leader later came out and said his own research was misunderstood and somewhat debunked, in that alphas are not leaders all the time and doesn't mean to take charge of things all the time.
