The document discusses two hypotheses about how tourists' worries and risk judgments may change following the November 2015 Paris terror attacks. The first hypothesis is that worries and risk judgments will sharply increase in the short-term. The second hypothesis is that in the long-term, tourists' perspectives will remain within expected margins and may even decrease slightly compared to before the attacks. The document provides theoretical support for these hypotheses from literature on tourism patterns following crises, gambler's fallacy, and factors like media coverage and government responses that may influence risk perceptions over time.
