Every organisation that publishes a psychological tool has to make a choice about tone. Hedge everything up front, and you undersell work that deserves confidence. Oversell it, and you’ve made a claim the evidence can’t actually carry. We’ve deliberately chosen the harder middle path.
Say what Lux does well, in plain and confident language, and never say more than the evidence supports.
Confidence first, not confidence instead of rigour
Foundation Nova Diem exists to build psychological tools that start from strengths and patterns, not deficits and categories. We think that’s worth saying plainly and proudly, not as a claim we immediately need to qualify away. Our flagship assessment, Lux, gives people language for how they think, relate, respond and grow, and we lead with that, because it’s true and it’s the whole point of building the thing.
But confidence about Lux’s purpose and design does not turn active evidence development into completed Lux-specific validation results. That is the boundary this claims standard sets.
What “held to evidence” actually means day to day
In practice, this standard is supported by concrete engineering controls and publishing rules:
- Every scoring pathway is versioned. If a result was produced by an earlier version of the engine, that’s traceable, not silently absorbed into “the current version.”
- Scoring changes are checked with committed fixtures and regression tests. Selected outputs are compared with defined reference values during development; this is not a claim that every output is independently revalidated before every report.
- Public claims should identify the evidence that supports them. A source-bank reliability figure should be described as source-bank internal-consistency evidence, not stretched into a broader claim about validity, outcomes or fitness for a use case it has not been tested against.
- We describe evidence development as work in motion. Test–retest evaluation, for example, is part of the active programme and will assess score stability as repeat-response data becomes available. We do not present the study or its result as complete before it is.
Why this is the discipline, not a weakness
It would be easier, in the short term, to write marketing copy the way most of the assessment field does: lead with the number, skip the caveat, let the reader assume more than the study actually showed. We think that approach quietly erodes trust in the whole field over time, and we’d rather not participate in it. Our aim is to make each claim traceable to evidence and open to correction when it gets ahead of that evidence. That discipline makes the limits of psychological insight easier to inspect.
