The Path of Least Resistance

I'm always jealous when better people than I formulate a thought I'd been circling around for years. In this case it's Michael Sherlock's tweet sporting this image. I'm impressed by his succinct description of the consequences of non-skeptical thought.

Critical thinking and scientific skepticism are the filters required for producing rational statements of probable truth. Without these filters our brains will inevitably follow the path of least resistance and succumb to credulity, supernaturalism and all manner of magical thinking.

I'm unable to find a source for this on the web, leading me to believe that this is taken from Sherlock's new book. I don't yet have confirmation.
