The antonym for the word "more observative" is "less observative." It means being less attentive, less vigilant, and less careful in observing things around you. Being less observative could lead to missing important details or events that could be crucial in understanding a situation. While some people might prefer being less observative to avoid being overly sensitive or judgmental, it is essential to balance observation with perspective and judgement. In some cases, being hyper-observative might also lead to anxiety or paranoia. Therefore, it is crucial to find a balance and not lean too much either way.
