A concept is a lens, not a diagnosis. Each entry separates what the idea can help explain from what it cannot establish.
Expectations and context can influence experience and behavior. Phroneme teaches this openly and never uses deception as a coaching tactic.
Boundary: An expectancy effect does not mean symptoms are imaginary, and it does not justify withholding effective care.
Living systems adjust to repeated conditions. A useful routine can become easier, while a training stimulus may need careful progression.
Boundary: Adaptation is not proof that more intensity is better or that every response is beneficial.
The frequency illusion occurs when attention and selective noticing make a newly learned idea seem suddenly common.
Boundary: Noticing something more often does not show that its true frequency increased.
Some repeatable behaviors can make other desired actions easier by changing cues, time, or friction.
Boundary: There is no universal keystone habit, and the label does not establish a biological mechanism.
In ecology, a keystone species has a disproportionately large effect on an ecosystem relative to its abundance.
Boundary: Phroneme uses this only as an explicitly labeled analogy for interconnected routines, not as a human-health mechanism.
