attention

Your brain misses information for a split second daily.

The attentional blink is a temporary deficit in reporting a second target when it follows a first target in rapid succession.

It is not a complete suppression of stimuli, but a capacity-limited bottleneck in retrieval; the timing window is typically 200–500 milliseconds.

You are literally blind to parts of your reality every day.

Where this comes from

Study: Raymond, Shapiro, & Arnell, 1992
What the check found: The core phenomenon is real, but the description of the brain 'ignoring it entirely' is an inaccurate simplification of a complex processing delay.
Confidence: Solid, with limits

One of these every day, and every one names the study it came from. When a finding is contested, it says so.
