Your Brain Prefers Pictures Over Words
Humans remember images far better than written text. Evolution has hardwired our brains to prioritize visual information as a survival tool, while reading remains a complex, recent invention.
Because our ancestors relied on sight to navigate and survive, the brain evolved to process visual input almost instantaneously. In contrast, reading requires the labor-intensive process of decoding abstract symbols into meaning. This is why you will likely forget a list of grocery items but instantly recall a photo of the shelf. By pairing text with an image, you can effectively hack this evolutionary preference to boost your memory.
