A man is running. Is it safe to assume he has two legs? Yes, because normally people who run have two legs. Does it make it 100% true? No, but there is a high likelihood that it is. Reckless would be to assume the opposite of what is normal is true. These cases are normally taken on contingency. There is no evidence indicating otherwise. Its not reckless to assume this case is being taken on in a normal and customary manner.
