Somewhat off-topic, but just thought I'd throw in my $0.02

It might be best to think of a scientific theory like a mathematical model. If I look at a graph of a thousand data points and see a line, the simplest and most reasonable assumption is that the predictor variable and the predicted variable have a linear relationship. I could conceive of a more-complicated formula that still explains the data, but until I get more data, the most reasonable assumption is that there is an underlying linear relationship.
