This is also a good opportunity for people to understand the difference between being uninterested and disinterested in a subject. Two words most won't really care to differentiate.

Ideally, you would want a researcher to be disinterested in the topic they study, but not uninterested. Meaning, they have no preferences as to what the outcome will be but are interested in finding the right answer.

It's a tricky thing to live out in practice, but most scientists I've come to know through work and studies have a level of respect for the scientific method and the collective pursuit of truth at all cost, that they do fairly well.

But the short answer is of course that this is why you need experiments that are easily repeatable ;)
