Superstimuli

The Speckled Egg
Birds will ignore their own eggs to sit on a giant, fake, polka-dotted model. It triggers their "Egg" instinct more than the real thing.
This is a Superstimulus.
Humans do the same. Pornography is a superstimulus for mating. Junk food is a superstimulus for foraging. Video games are a superstimulus for agency.

The Mechanism (D2 Downregulation)
The brain protects itself from over-stimulation by downregulating D2 Dopamine Receptors.
- Tolerance: You need more of the stimulus to feel "normal."
- The Crash: When the stimulus (drug/screen) is removed, you have below-baseline sensitivity. This is Anhedonia.
The Coolidge Effect
Why do we swipe? The brain acts as a Novelty Seeking Engine.
In biology, a male rat will exhaust itself mating with one female. Introduce a new female, and he immediately recovers. This is the Coolidge Effect.
Apps like Tinder weaponize this biological refresh rate, creating an infinite loop of "New."
The Pleasure Trap
We evolved in a world of scarcity. We have no "off switch" for abundance.
When you offer a Stone Age brain infinite dopamine, it does not self-regulate; it consumes until it breaks.
The Inheritance of Perspective
The modern world is designed to hack your instincts. Every app, every ad, every flavor is engineered to be a specked egg. To be free is to recognize the trap. Choose the real, even if it is less shiny. The real nourishes; the fake only simulates.
