Thought leadership strategy is not about proving your intelligence to customers, but rather it’s about moving beyond “showing off” and actually providing something of value.http://contentmarketinginstitute.com/2013/08/thought-leadership-strategy-using-research-wisely/
To be a "Thought Leader" you have to share the really valuable stuff, the stuff you would probably like to keep to yourself.
"Like wetting your pants in a dark suit, you get a warm feeling but nobody notices."
The problem with keeping it to yourself is that no one else will ever know that you have these remarkable insights. You can't get credit for them, or stand out from the crowd, or be sought after as the result of developing these great ideas and ground breaking theories.
The argument that "Then my competition will know it, too" is invalid because you'll know it first and you'll know it best.
