Here are a couple reasons.
1. What they’re doing isn’t working.
Someone is trying to achieve a result, but isn’t achieving the desired result. If achieving the result is important to them, they will tend to care about relevant truths.
2. They believe they could be doing something that would work.
Someone comes to a belief that they could do something (or do something much better), and so relevant truths become important.
Which is to say, technology is a demonstration of truth.
In this sense, technology forms the metaphysical basis for robust science (not the other way around). Put another way, we believe certain theories because they seem to be demonstrated in certain technologies.
