Crime & Mystery
Crime fiction gets dull fast when the science starts behaving like a butler with a notebook.
A forensic detail should usually do one job: make the world feel solid. Past that, it can begin to solve the case for you, and then the detective is just standing there while the lab report has all the fun. The best mysteries leave a bit of grit in the gears. Real enough to convince, fuzzy enough to leave room for bad judgement, pressure, and human error. Science is useful. Over-explaining it is often just a tidy little way of killing suspense.

The bigger problem is when the science becomes the only honest person in the room. Then every suspect is just waiting for a printout to accuse them.
In practice, most cases are messy because the evidence is partial, contaminated, or interpreted by people with deadlines. That’s where the tension lives. Not in whether the lab can do a clever trick, but in how much weight anyone should give it.
