<p>Is there a well-studied cognitive bias that describes a situation in which a person expresses a positive attitude towards something because his or her's friends have a positive attitude about that thing as well?</p>

<p>I am speaking mostly in the context of social networks - people pressing the "Like" button on Facebook because they saw that their friends have liked a certain something as well.</p>

<p>I've read about the <a href="http://en.wikipedia.org/wiki/Bandwagon_effect" rel="nofollow">Bandwagon effect</a> but that doesn't quite seem to fit my description exactly - mostly because it seems to apply to how one's beliefs are influenced by one's peers.</p>

<p>What I am looking for is something that describes the situation in which a person likes something independently of what others tend to think, but the person's decision to actually share that liking attitude to the world is triggered by seeing that others have shared that positive attitude already.</p>

<p>Also, if you have a list of articles on this subject, I would be very grateful if you shared them.</p>

# Cognitive bias - Confirming the attitudes of your peers

(Asked by: username_0 on 2014-10-19)

Is there a well-studied cognitive bias that describes a situation in which a person expresses a positive attitude towards something because his or her's friends have a positive attitude about that thing as well?

I am speaking mostly in the context of social networks - people pressing the "Like" button on Facebook because they saw that their friends have liked a certain something as well.

I've read about the [Bandwagon effect](http://en.wikipedia.org/wiki/Bandwagon_effect) but that doesn't quite seem to fit my description exactly - mostly because it seems to apply to how one's beliefs are influenced by one's peers.

What I am looking for is something that describes the situation in which a person likes something independently of what others tend to think, but the person's decision to actually share that liking attitude to the world is triggered by seeing that others have shared that positive attitude already.

Also, if you have a list of articles on this subject, I would be very grateful if you shared them.
