- No.

Do notifications hurt performance?
Even unused notifications can pull attention. Lab and classroom studies often find costs on the current task. Costs are not a Wechsler Full Scale IQ.
What is media multitasking?
Some surveys link heavy media multitasking with worse performance on certain attention tasks; other work is mixed or confounded by who chooses to multitask. Treat viral summaries with caution.
Is this an addiction diagnosis?
No. This explainer is not a clinical screen for gaming or phone-use disorder.
Can I “train away” phone distraction with games?
Unlikely as a general cure. Flanker-lite and task-switch-lite let you feel conflict and switching. They do not certify digital wellness.
IQ vs attention again?
Attention supports many test items; it is not identical to g. A distracted run is a bad sample of either.
How should I practice here?
Silence the phone, then try flanker-lite or visual-search. Still not an IQ.

Test–Retest Reliability
If you take a test twice, the number often moves. Psychometrics calls the stable part reliability and the bouncing part error, practice, mood, sleep, or a different form. A web game score is especially noisy.
Test–Retest Reliability →What Is a Standard Score?
Raw scores (items correct, milliseconds) are not comparable across ages or tests. A standard score rescales them so that, in a reference sample, the mean and spread are fixed. This site does not convert game hits into that scale.
What Is a Standard Score? →IQ and Job Performance
Industrial-organizational research often finds that general mental ability predicts job performance better in more complex roles, with validity coefficients that are real but far from 1.0. This article is descriptive. It is not a recommendation to choose or reject a career from a web score.
IQ and Job Performance →Nutrition and Cognition
Brains run on ordinary metabolism. Skipping meals, dehydration, and extreme restriction can make attention feel worse in the short run. That is not the same as a supplement raising IQ, and this site does not sell or endorse pills.
Nutrition and Cognition →Heat and Test Scores
Hot, poorly ventilated rooms make many people slower and more irritable. Research on ambient temperature and exam or cognitive-task performance is mixed but often points to discomfort and attention costs — not a rewritten intelligence.
