What does “解像度が高い” mean outside of cameras?

In this book-recommendation video, the speaker praises a book for teaching how 解像度が高い人 (“high-resolution people”) gather information and think. 解像度 is originally a technical term for image or display sharpness, but it’s become a fixture of modern Japanese business vocabulary, describing how clearly and specifically someone understands a problem rather than how sharp their eyesight is.

Someone with 解像度が高い thinking can move fluidly between concrete detail and abstract concept, spotting specifics a vaguer thinker would miss. The flip side, 解像度が低い (“low resolution”), describes fuzzy, underdeveloped understanding, and 解像度を上げる (“raise the resolution”) is now common shorthand in meetings and pitch decks for “get more specific.” Much like English speakers borrowing “bandwidth” from networking to mean mental capacity, Japanese speakers have quietly repurposed a camera-and-display term into one of the most common ways to compliment — or criticize — how someone thinks.
