Human multitasking is a myth because the brain switches tasks sequentially
the verdict
SUPPORTED
the evidence backs this
confidence 92/100
Cognitive and neuroimaging research demonstrates that true simultaneous mental processing of multiple demanding tasks is constrained by a central bottleneck, causing the brain to rapidly switch between tasks in a sequential manner.
