How the Mind Works
Discover how the human mind turns raw sensory input into thought, memory, and conscious decisions. Explore the hidden mental architecture that shapes how you perceive reality, solve problems, and communicate. Gain a clear, unified view of cognitive science without getting lost in academic jargon.
Like Duolingo, but for How the Mind Works. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
24 levels across 4 sections, about 48 minutes end to end, roughly 10 days at five minutes a day. It moves through Filtering and Interpreting Reality; Memory, Meaning, and Language; Reasoning and Problem-Solving; and The Architecture of Thought. It starts from scratch.

Key ideas in How the Mind Works
- Sensory organs continuously collect vast streams of physical information from the environment
- Conscious awareness acts as a narrow bottleneck that admits only a tiny fraction of incoming sensory signals
- Sensations not deemed immediately relevant are filtered out before reaching conscious perception
- Inattentional blindness occurs when high focus on one task prevents conscious awareness of an unexpected object
- Direct visual gaze alone does not equal visual perception; the brain's attention system must actively process the image
- Even visually prominent or brightly colored objects can go entirely unnoticed during focused attention
- The brain cannot consciously process two cognitively demanding, goal-directed tasks at the same exact time
- What feels like simultaneous multitasking is actually rapid task-switching
- Every switch between tasks carries an unavoidable cognitive cost in time, mental effort, and error rate
- Selective attention works both by boosting target sensory inputs and by actively suppressing distracting inputs
- Suppressing background noise is an active neural effort, not merely passive absence of hearing
- High-salience signals, like hearing one's own name, can punch through suppression filters
- Resisting tempting sensory cues requires active cognitive control that exhausts mental resources over time
- Removing distracting stimuli from the physical environment bypasses the need for continuous neural suppression
- Modifying environmental context preserves cognitive bandwidth far more reliably than effortful willpower
- The eye receives incomplete, noisy signals with blind spots and low peripheral resolution
