Furthermore, many fall into the trap of believing that there is a finite number of alternative hypotheses: so if all but one are falsified, the remaining one would have to be true..

From that well known philosopher, Sherlock Holmes:

“When you have eliminated all which is impossible, then whatever remains, however improbable, must be the truth.”

“It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts.”
