The occasional fallacy is a fallacy of "general rules overriding exceptions", which is based on the existence of a general rule and denies the existence or justification of exceptions. According to the above definition, there are occasional fallacies in the following reasoning:. ['Eating meat will make you fat, so vegetarians will definitely lose weight.', 'Speeding is illegal, so ambulances should not be speeding.', 'All horses can be trained as war horses, so seahorses can also fight horses.', 'I lived in Hong Kong for seven days and it rained for three days, so it rained about half of the time in Hong Kong.']
