Answer:
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.
