You Make my Decision

Are we in control of our decisions? I'm suppused to answer yes, but Dan Ariely show you the otherwise. In this video he has some impressive arguments. Our vision mislead us with color and size. Our decisions are made by illusions. And without knowing, you're directed by other things or other people, like media, advertissements,  and designers. We think that we have all the time the posibility to choose, but our decision is all the time guided by what's happening outside of us.
