I learnt this later in my career about a decade and half ago .. by default.. I learnt it was very useful, I was more respected and taken more seriously.. I actually did it as I was disenchanted with the corporate world .. was shirking.. but it had a counter indicative effect.
Earlier when I was knowledgeable hands on and vocal .. I felt victorious and appreciated within my inner circle and coterie.. the larger group or people resented it.
Inaction sometimes is also an action. I learnt, atleast in meetings...especially in the Corporate world ..
