Arl is the one person Craig has ever met from New Zealand. Carl strikes Craig as being quite friendly and funny. When asked what he would expect to find if he went to New Zealand, Craig says that he would expect the people to be quite friendly and funny. What might he have used to make this judgment?

Fallacy of Hasty Generalisation

Explanation:

Craig has fallen into the danger of generalising or hypothesizing about the behaviour of one group of people based on a very small population sample (Arl).

Craig believes that because he has met Arl who is from New Zealand and seems nice, then all the people from that country are nice,friendly and funny. This might not be the case as there are several factors that could determine the behavioural disposition of a person which could include genes, experience, upbringing and environment and this is sure to vary from person to person.
