threshold setting principles

Threshold Setting Principles

Document Positioning: This document provides a unified explanation of thresholds in various mechanisms of Stairway Universalism. It does not attempt to package specific values as philosophical necessities, but explains what institutional functions these values serve and when they must be corrected.

I. Why Threshold Principles Are Needed

Stairway Universalism already uses thresholds in multiple documents: capability measurement singularization, solidification rate, objection adoption rate, baseline service user quality gap, audit error rate, feedback fund collection rate, etc.

Without unified explanation, these thresholds would appear arbitrary. This arbitrariness weakens institutional credibility.

The core judgment of this document is: Thresholds are not justice itself, but triggers for institutional action. Different thresholds are different because they correspond to different types of risks.

II. Three Types of Thresholds

2.1 Rights Baseline Type Thresholds

Definition: When an indicator directly relates to citizens' basic rights, life safety, minimum dignity, or baseline universal layer quality, thresholds should be set higher.

Typical Indicators:

Baseline service user service quality must not fall below a certain bottom proportion of the equivalent scenario standards of high-risk threshold holders. Specific values are determined by domain and era conditions, must accept regular review and protective correction.
Feedback fund collection rate must not be chronically below a certain bottom proportion.
Accessibility of critical public services must not show systematic group differences below standards.

Reason for Setting: Rights baseline type indicators are not ordinary performance indicators. Once they decline, the damaged are often baseline service users or the least advantaged. For such indicators, the system cannot wait until serious deterioration to initiate action.

Principle: Rights baseline type thresholds should adopt high sensitivity. It is better to trigger rectification early than to let baseline service users suffer irreversible damage for the long term.

2.2 Structural Risk Type Thresholds

Definition: When an indicator reflects whether the stairway is solidifying, definition power is concentrating, or capability measurement is becoming singularized, thresholds are used to identify structural tilts.

Typical Indicators:

A certain socioeconomic background accounts for too high a proportion in a certain risk threshold position (such as triggering alert when exceeding a certain proportion).
A single capability type accounts for too high a proportion among the highest risk threshold holders.
A single institution dominates standard-setting and excludes objections, triggering definition power concentration alert.

Reason for Setting: Structural risks do not always manifest from single events, but are shown through long-term distribution patterns. Structural indicators need to simultaneously focus on concentration, duration, and improvement trends.

Principle: Structural risk type thresholds should adopt a dual-threshold design. Yellow thresholds are for warning and review; red thresholds are for freezing and reconstruction.

2.3 Procedure Health Type Thresholds

Definition: When an indicator reflects whether procedures such as appeals, objections, audits, and reconsiderations are truly effective, thresholds are used to judge whether the system only exists in form.

Typical Indicators:

Objection adoption rate is chronically too low for multiple consecutive years.
Degradation appeal success rate is chronically too high for multiple consecutive years.
Audit error rate is chronically too high for multiple consecutive years.
Re-promotion rate is chronically too low for multiple consecutive years.

Reason for Setting: Procedure health type thresholds do not directly indicate result justice, but indicate whether correction mechanisms are alive. Objections never being adopted may mean institutional closure; appeal success rates being too high may mean original judgments are too hasty; re-promotion rates being too low may mean degradation becomes a lifetime stigma.

Principle: Procedure health type thresholds should focus on abnormal patterns, rather than pursuing some simple "the higher the better" or "the lower the better" goal.

III. Five Rules for Threshold Setting

3.1 Thresholds Must Explain Trigger Actions

Every threshold must answer: What happens after it is exceeded?

Optional actions include:

Public warning
Independent review
Suspend new admissions
Launch special audit
Mandatory rectification
Enter local or systematic reconstruction procedures of the self-negation clause

Thresholds without trigger actions are merely decorative numbers.

3.2 Thresholds Must Distinguish Yellow and Red Zones

Yellow thresholds indicate that the system needs explanation and review; red thresholds indicate that the system must freeze or reconstruct.

Yellow thresholds should not automatically lead to punishment. Their function is to prevent problems from being dragged to irreversible stages.

Red thresholds should not depend on the approval of those in power. Their function is to transform reconstruction from political will into institutional obligation.

3.3 Thresholds Must Combine with Duration

A single anomaly does not necessarily indicate structural collapse. Most structural risk indicators should require continuous appearance for a period, such as two consecutive years, three years, or five years.

But rights baseline type indicators are exceptions. When involving life safety, legal relief, and personal freedom and other irreversible damages, a single serious fall can also trigger emergency review.

3.4 Thresholds Must Allow Protective Correction

Thresholds are not shields for institutional self-protection. If actual operation shows that baseline service users have already suffered systematic harm before reaching the threshold, the threshold must be protectively corrected: raising protection requirements, lowering trigger tolerance, or initiating review in advance.

For example, if the solidification rate has already caused strong exclusion effects when below the established threshold, one cannot insist on "not yet at threshold so no need to deal with it." The threshold is the minimum trigger line, not the upper limit prohibiting early action.

3.5 Thresholds Must Publicize Their Uncertainty

Any threshold contains empirical judgment and political judgment. The system must publicly acknowledge this.

The correct formulation is not: "A certain proportion is the boundary between justice and injustice."

The correct formulation is: "Under current experience and risk tolerance, a certain proportion is set as a mandatory reconstruction trigger point; this value must accept regular review."

IV. Summary

Thresholds are not the mathematization of justice, but switches for institutional self-doubt.

Stairway Universalism cannot claim that a certain number is naturally justified. It can only say: To prevent power structures from solidifying in silence, we preset some public, questionable, and correctable trigger lines. Once triggered, the system must explain, rectify, or reconstruct.

Institutional Engineering Honesty: The value of thresholds lies not in precision, but in preventing those in power from infinitely delaying the acknowledgment of risks.
