Sadia Omita's post on Goodwall - We often judge a book by its cover, which is a 'halo effect'. It is a psychological nature of ours where we tend to factor out other important features of a person or a thing and form a comment about it on the basis of a single attribute. It leads us to a wrong way. To make a sound judgement on anything we shouldn't let this halo effect cloud our vision. Inspired by "The Art of Thinking Clearly".
