Introduction The question of whether the UK education system reproduces social inequality is central to sociological debates about meritocracy and social mobility. While official discourse often presents education as a great leveller – a mechanism through which talent can overcome background – a substantial body of sociological evidence suggests the opposite. This essay will argue …

Aggression is a pervasive and complex behaviour that has attracted substantial theoretical debate within psychology. This essay will evaluate two prominent psychological explanations: the biological perspective, which emphasises innate mechanisms such as serotonin and testosterone, and the social learning theory (SLT) proposed by Bandura (1973, 1977), which stresses observational learning and environmental reinforcement. Each perspective …
