why is the rejection of a hypothesis helpful to scientists?

Answer 1

You typically generate a series of different hypotheses that can explain your observations, then try to design experiments that seperate them so you can find the one that works. Rejecting a hypothesis is much easier than proving it. Once all the wrong ones are gone, you have a solid theory.

Answer 2

Scientsts know that the hypothesis is not correct and can eliminate it so they don't have to test it again. They can come up with a solution through the process of elimination.

Answer 3

It eliminates having to observe or measure certain events or objects.

You see a red balloon.

You hypothesize all balloons are red.

One green balloon disproves the hypothesis.

It also helps eliminate other hypotheses.

For example, we know better than to postulate all balloons are green.

And it leads us to a far better hypothesis:

Balloons can be manufactured in any color.

Answer 4

Because it allows them to rule out an incorrect theory, which in turn allows them to focus their attention to an alternative theory which now has a greater chance of being correct.

Answer 5

According to Arthur Conan Doyle's Sherlock Holmes, "after you have eliminated everything else, what is left must be true"

Answer 6

Because science works by ruling OUT falsities, so that whatever explanations are left, are more likely to be true.

Answer 7

So they know what DOESN'T work, so in the future, they'll know what chemicals or procedures to avoid.

Answer 8

It tells something that didn't work, so it need not be tried again.
