If you ever visited a neighboring country and found that the people there had little or no connection to your own country’s culture, language or even physical appearance, it’s only natural that you wonder how this can be; after all, if the countries share a border, they have to resemble many traits?? Not really. It [...]

Decision-making could be unconscious

Tue, Apr 15, 2008
