Hypothesis · StartupBuilder

Experiments test it, and Evidence grades it.

Properties

Property	Type	Required	Description
`statement`	`text`	required	The belief, in one sentence.
`kind`	`string`	required	One of `founding`, the five slots (`customer`, `problem`, `approach`, `switch`, `differentiation`), or `loop`.
`parent`	Hypothesis		The Founding Hypothesis a slot Hypothesis belongs to.
`verdict`	`string`	required	One of `Open`, `Testing`, `Supported`, or `Refuted`.
`metric`	Metric		The Metric that settles it.
`threshold`	`string`		The Metric value that settles it.
`grade`	`string`		Computed: the strongest grade of its outside Evidence, `None` without any.
`version`	`integer`	required	Each merged Change adds one; outputs cite it in their lineage.

Relationships

A Hypothesis has many pieces of Evidence: Evidence supports or refutes Hypotheses; the strongest outside Evidence sets each Hypothesis grade. evidence, inverse bearsOn.
A Hypothesis is a slot of one Hypothesis: the five slot Hypotheses of a Founding Hypothesis, each with a Metric and a threshold. slotOf, inverse slots.
A Hypothesis’s slots are many Hypotheses: the five slot Hypotheses of a Founding Hypothesis, each with a Metric and a threshold. slots, inverse slotOf.
A Hypothesis is stated by one Startup: a Startup states Hypotheses about itself, the Founding Hypothesis first, each settled by a Metric and a threshold. statedBy, inverse states.
A Hypothesis has many Stories: the Founding Hypothesis whose slots the Story compiles from; a pivot recompiles it. stories, inverse compiledFrom.
A Hypothesis is tested by many Experiments: each Experiment settles one Hypothesis; many Experiments test one Hypothesis in turn. testedBy, inverse tests.
A Hypothesis is tested by opening one Opening: a hire into an Opening must prove its Hypothesis. testedByOpening, inverse tests.

Lifecycle

State	Meaning	Moves to
`open` (first)	Stated with its Metric and threshold, and bound to no Experiment.	`testing` by Hypothesis.test; `dropped` by Hypothesis.drop
`testing`	An Experiment that decides it is running.	`supported` on `Experiment.concluded` when the Experiment’s Metric met this Hypothesis’s threshold; `refuted` on `Experiment.concluded` when the Experiment’s Metric missed this Hypothesis’s threshold; `dropped` by Hypothesis.drop
`supported`	Its Experiment met the threshold; its outside Evidence grades how far that holds.	`testing` by Hypothesis.test; `dropped` by Hypothesis.drop
`refuted`	Its Experiment missed the threshold; a merged Change can restate it and test it again.	`testing` by Hypothesis.test; `dropped` by Hypothesis.drop
`dropped`	Retired from active work and kept on record with its Evidence.	None: it ends here.

Test the latest hypothesis with an experiment.

"Dental offices pay $99 a month to halve no-shows" is a Hypothesis with metric paid offices. Twelve paid offices within 30 days of the reservation link going out set verdict: Supported; fewer than four set Refuted.
