Welcome. I keep forgetting how I know things. With so much of life transpiring through screens — Zoom calls, group texts, long articles saved to read later, Netflix series half-paid-attention-to while scrolling through Instagram — I’ll find myself recalling a fact or a story, unable to identify the source of the information. Did this dimly recollected tale of, say, getting stranded in a blizzard come from a friend or colleague? Did I hear about it on a podcast? Is it a vignette from a movie I watched part of and then abandoned? How do I know what I know? What is fact and what is fiction?
