When I was a kid, I went on many camping trips with my mom and stepdad. One one such trip, we camped near sand dunes because my mom was writing a book called Seasons of the Wind. It's about plant life on sand dunes in the southwest United States.
I remember hiking in the sand, putting one foot in front of the other. Forward progress was surprisingly difficult. Step, sink, pull, repeat. And standing at the top of a dune was dizzying; they seemed to move, almost breathe.
Since 2011, I've felt a bit like I'm back on that dune, the sand shifting under my academic feet. Am I doing this right? What findings can we trust? What the hell is evidence anyway? Maybe I never really knew anything to begin with. Maybe this sand will pull me under.
