A well-structured account of the current debate concerning the role of a person's genes and environment in determining their intelligence, personality and behaviour.
The strengths of the essay are to be found in the latter stages where many of the writer's assertions are supported by a number of relevant case studies. The reader is encouraged to draw their own conclusions from these investigations. Quite rightly, the writer points out that, since much of the research is on-going, it is too early to draw definitive conclusions. The jury is still out!
In the first part of the essay, however, there are a number of rather sweeping generalisations which are not supported by evidence derived from scientific investigations.
Overall, however, the writer communicates a real interest in the subject and gives the reader considerable food for thought.
