Conference Presentation.   Additional Information: This quote is from neuroscientist Molly Crockett's 2012 TED Talk about how scientific claims are often used in marketing -- often erroneously. The quote means that while scientists have made great strides in understanding the human brain, neuroscience has its limits. For example, scientists haven't figured out surefire ways to manipulate someone to buy something, to determine what people are thinking, or to drastically change someone's personality.
