Thomas Jefferson

Evidence can be messy. Because it is a mental construct, it rarely gives us the clear and simple answers that we seek. Sources, by contrast, are physical; we can touch them, see them, smell them, hear them. Information is also physical, visible, audible. Evidence, however, is intangible. It’s only what we think certain information means. That’s all it can be―until we make something concrete from it by processing it and molding it into a meaningful and convincing form.

How do we do that?
