Giant Brain Candy: The Worries That Never Came. People treated for chronic worry logged their worries for ten days and checked back 20 days later: 91.4% of the worries had not come true. Source: How often worries come true.
Giant Brain Candy: Check Again, Trust Less. People who checked a virtual gas stove again and again grew less sure they had checked it, as their memories grew less vivid, though their memory stayed just as accurate. Source: Repeated checking and memory.
Giant Brain Candy: Curiosity Makes Memories Stick. Curiosity engages the brain’s reward circuits and boosts memory: when people were curious about a question, they remembered its answer better, and even unrelated faces shown while they waited. Source: Curiosity, reward and memory.
