See my response to tonymet upthread.

For some theories that are called "scientific", yes, this is true--but that's because the scientists themselves don't have a track record of correct experimental predictions to begin with. (String theory, for example.)

But for theories like, say, General Relativity, there is a huge track record of correct experimental predictions, and those predictions include things in our everyday experience now, like GPS. It's true that most people cannot verify for themselves the entire chain of reasoning that leads from the Einstein Field Equation to how their GPS device works, but they know that GPS works from their personal experience, so they know that whatever theory scientists are using to make GPS work, works. They don't have to take that on trust.

In other words, for scientific theories that actually have practical impacts, you don't have to just accept what scientists say on trust; you can look at their track record of correct predictions.
