is also true. Attitude similarity has also been found to serve as a strong foundation for long lasting friendship. Friends who share a similar interest in activities where more likely to perceive similarity and liking then those who shared similar attitudes. An individual's perceived similarity with another has been proven to show potential for romantic relationships even though actual similarity was reported to be low. These findings explain that individuals are more likely to be attracted to those who they perceive to share similar activities with such as occupation and hobbies. Propinquity also explains the relationship between liking and activities, those with similar interests tend to put themselves into similar types of settings increasing their chances of interaction. As frequency of interaction between 2 or more people increases, the degree of perceived similarity and liking for one another increases eventually leading to long lasting relationships. Several explanations have been offered to explain in what way similarity increases interpersonal attraction (like-prefers-like). First, people with similar interests tend to put themselves into similar types of settings. For example, two people interested in literature are likely to run into each other in the library and form a relationship (involving the propinquity effect). Another explanation is that we notice similar people, and expect a relationship to be interpersonally validating and beneficial because of similar attitudes, behaviours and values. People are susceptible to making negative judgements about those who are 'out of group' than 'in group' from them socially, behaviorally or of different morals and values. Specifically, the 'Big Five' personality trait dimensions (extroversion and introversion, agreeableness and disagreeableness, openness and closeness, conscientiousness and apathetic, as well as mental stability and neuroticism) are behavioural traits often used to assess similarity or dissimilarity in relationships.
