    Question Certitude of results

    Whyis it easier to disprove something than to prove something?

    Why can you havemore certainty of something being untrue?

    Why is it hard tosay something is true if the experiment's result yields it being true? Why is it a 'big maybe'?

    Re: Certitude of results

    Because all it takes is one example to disprove something, but it takes an infinite amount of examples to prove something. For example: from experience you can expect that if you let go of a pencil it will fall, but you can't prove that the pencil will always fall. However, it's easy to disprove the contention that if let go of a pencil it will hover in mid-air and not fall - all it takes is one trial to disprove.
