Re: Bias?
"Not-real-friends" is the answer. If you have "weaker connections" or anti-social traits and you're getting jobs through LinkedIn's "friends"... they're not really your friends. A real friend that gets you a job doesn't use LinkedIn to do it. So, it's no surprise this isn't tracked accurately on LinkedIn because a LinkedIn doesn't accurately describe "friend". You can dive down in the fish bowl looking for more answers but, really the data isn't there because your real friends aren't :-/
