Anti-social

Anti-social behaviour is that lacking in judgement and consideration for others, ranging from careless negligence to deliberately damaging activity (e.g. vandalism and graffiti). Someone behaving in an anti-social manner may be a manifestation of an antisocial personality disorder.

The term "anti-social" is often mistakenly used to describe someone who is introverted. People who are anti-social can also be extroverted, however.

Anti-social behaviour in the UK
In 2003, the British government proposed legislation to counter anti-social behaviour - the Anti-Social Behaviour Act 2003. This introduced Anti-social behaviour orders, which are civil orders which if broken can result in imprisonment of up to five years.

The Crime and Disorder Act 1998 defines anti-social behaviour as acting in a manner that has "caused or was likely to cause harassment, alarm or distress to one or more persons not of the same household" as the perpetrator.

The counterpart of Anti-Social Behaviour is Pro-Social Behaviour. Pro-Social Behaviour is any behaviour intended to help or benefit another person, group or society. To determine what is Pro-Social Behaviour, we observe the underlying goal motive that initiates and drives the behaviour rather than the actual outcome of the behaviour. True Pro-Social behaviour is intentional.
