"The lasting effect of first impressions is known to psychologists as the 'halo effect': if you can snare people with an attractive design, they are more likely to overlook other minor faults with the site, and may rate its actual content (such as this article, for example) more favourably.
This is because of 'cognitive bias', Lindgaard explains. People enjoy being right, so continuing to use a website that gave a good first impression helps to 'prove' to themselves that they made a good initial decision."
