Research reading note
Why context belongs beside a trait.
A tendency is useful information. The circumstances around it help us ask better questions.

The idea to take with you
Read a trait as a pattern to explore, with room for the situation. A position does not explain every moment—or establish why two reports differ.
The tidal pool is an illustration of context, not research data.
A pattern and a moment
You might enjoy a lively evening with friends and prefer a quiet morning the next day. A report should leave room for both accounts.
Fleeson’s 2001 research used repeated reports of everyday personality states. It found substantial variation within people alongside stable differences in their average states. Recurring tendencies do not mean identical behavior in every moment. [1]
Our design implication is to put context beside the interpretation. That is a choice about the reading experience, not evidence that our assessment has been validated.
Read the scale
The International Personality Item Pool’s guidance cautions against turning continuous scores into fixed types, and discusses the reference samples needed to interpret scores relative to others. [2]
Our example scales do not show population percentiles, diagnostic cutoffs, or validated scores. The description explains the intended interpretation.
| What you see | What to check |
|---|---|
| A scale position | What does each end mean? Is this measured data or an illustration? |
| A percentile | Which reference group, instrument, and scoring method does it use? |
| An interpretation | Which observations support it, and where might it not apply? |
Comparing two moments
Start by checking what is actually being compared. Were the same definitions and scoring method used? Was evidence missing? What uncertainty belongs to the estimate?
Then ask about the circumstances. Different stories, time available, or settings are questions to investigate, not explanations we can assume.
In our comparison, both dates and all positions are invented. Neither end is a goal, so differences are not labeled “improved” or “declined.”

The cited studies and guidance do not validate a video-based 99traits assessment. They address other methods and questions. Our thirty dimensions are a demonstration taxonomy, not a published instrument.
Claims about measured traits or change would need evidence for the specific instrument, scoring process, population, and use. This note does not provide reliability estimates, accuracy figures, or a threshold for meaningful change.
