Meanings

Adjective

  1. based on observing and recording rather than intervening or experimenting

  2. good at noticing details; inclined to observe carefully

Beyond the definition

"Observational" describes something related to carefully watching and noting what happens around you. Think of a wildlife filmmaker—their work is entirely observational, capturing animals in their natural habitat without interfering. It is about gathering information through direct experience rather than through experimentation or guesswork.

You might describe someone as "observational" if they are exceptionally good at picking up on subtle cues and understanding people's behavior. Observational humor, famously associated with comedians like Jerry Seinfeld, finds its laughs by pointing out the everyday quirks we usually overlook. It can also refer to a specific type of research; observational studies in medicine track what happens to groups of people over time without attempting to change their lives or environment.
