Human behaviour is experienced throughout an individual’s entire lifetime. It includes the way they act based on different factors such as genetics, social norms, core faith, and attitude. Behaviour is impacted by certain traits each individual has. The traits vary from person to person and can produce different actions or behaviour from each person. Social norms also impact behaviour. Due to the inherently conformist nature of human society in general, humans are pressurised into following certain rules and display certain behaviours in society, which conditions the way people behave. Different behaviours are deemed to be either acceptable or unacceptable in different societies and cultures. Core faith can be perceived through the religion and philosophy of that individual. It shapes the way a person thinks and this in turn results in different human behaviours. Attitude can be defined as "the degree to which the person has a favorable or unfavorable evaluation of the behavior in question."[citation needed] One's attitude is essentially a reflexion of the behaviour he or she will portray in specific situations. Thus, human behavior is greatly influenced by the attitudes we use on a daily basis.
