🧭 The Corner Test

Two axes make four corners. A common myth is that the “happy + excited” corner is the best place to be. It isn’t — which corner people prize is cultural (Tsai’s ideal-affect research). Every corner is a real, useful place.

pleasant + high energy

e.g. Excited — buzzy and good — but not the "goal" corner. Living here all day would be exhausting.

pleasant + low energy

e.g. Calm — many cultures prize THIS corner (calm contentment) over the loud one — Tsai's research.

unpleasant + high energy

e.g. Frustrated — a real, useful place — it is the feeling that says "something needs to change".

unpleasant + low energy

e.g. Gloomy — heavy and quiet — a real place too. It is not "bad", and it passes like weather.

🎚️ Why one slider isn’t enough

Some apps ask you to rate your mood on a single slider from bad to good. But feelings have two directions, not one — pleasantness and energy. A one-slider tracker can’t tell these apart:

Sad and Scared — about the same pleasantness (-0.68)… …but very different energy. Same pleasantness, but "sad" and "scared" have very different ENERGY — a one-slider mood tracker would record them as the same feeling.
Sad and Angry — about the same pleasantness (-0.68)… …but very different energy. Same pleasantness, but "sad" and "angry" have very different ENERGY — a one-slider mood tracker would record them as the same feeling.
Scared and Lonely — about the same pleasantness (-0.62)… …but very different energy. Same pleasantness, but "scared" and "lonely" have very different ENERGY — a one-slider mood tracker would record them as the same feeling.
Scared and Gloomy — about the same pleasantness (-0.62)… …but very different energy. Same pleasantness, but "scared" and "gloomy" have very different ENERGY — a one-slider mood tracker would record them as the same feeling.

That missing second axis is exactly what the Map puts back.

🔭 The two axes (a quick recap)

In 1980 the psychologist James Russell showed that almost every feeling word sits somewhere on a circle drawn from just two directions: pleasantness (cold ↔ warm) and energy / arousal (still ↔ stirred-up). Scientists later asked thousands of people to rate thousands of words on exactly those two dials — those open ratings are the “where most people put it” you reconcile against on the Map. The circle is a description of how people rate words, not a rule about how you should feel.
