Why the last chocolate tastes the best It is also possible that we have become used to expecting endings to be happy. He added: "When you simply tell people something is the last, they may like that thing more." In their study, the fed 52 male and female students five small chocolates of different flavours before asking them to rate their enjoyment as they ate. The flavours were ranked in different orders with some volunteers being told the chocolate was their last while others received no such warning. The study found those with the warnings found the last chocolate tastier than others. Asked which chocolate was their favourite, those which knew chose it on more than two in three occasions. In contrast, those who were unaware rated it top in only 22 per cent of cases. Mr O'Brien, a graduate student in social psychology, said that due to the chocolates being rated individually, rather than all together at the end of the experiment, meant the results could not be explained by difference in recall. He added: "Many experiences have happy endings - from the movies and shows we watch to dessert at the end of the meal - and so many people may have a general expectation that things end well, which could bleed over into these unrelated or insignificant judgments." He said the findings could have negative implications on other aspects of life such as examiners marking their final paper. Meanwhile, candidates who interviewed first for a job may be viewed less favourably than those who are seen last.
