In the case of outfits there seems to be a deeper psychological mechanism involved. I usually wear black jeans, but also have brown and blue ones. Black is more easily combinable with diffrent colors of shirts. So it is an easy choice in the morning: black jeans + any of my shirts. When I wear the brown shirt, I have to choose a bit more carfully, but it is not really a big deal. However, what I observe is that I fell always a bit uncomfotable after I made my decision to wear brown. It feels a little bit like I am in disguise. A have similar observation when going to some of my favourite restaurants. Even when I take my time to look through the menu, I very often choose the same dish or from only two or three standard alternatives, although I was actively deliberating to choose something else this time. It really seems that it is not only the effort of reaching a decision that is behind the default effect, but some unconscious risk-aversion process that does not allow the mind to rest easily in the non-default case.
