Methodology of the Polimetron Index

Our methodology quantifies individual political accountability as a composite score on a 0–1 scale. The specification includes Greece-adapted pillar weights, rigorous data quality safeguards, and verifiable indicator scaling across 24 pillars.

Overview

The Polimetron Accountability Index (PAI) is a 0–1 composite comprising six thematic categories expanded into 24 pillars and multiple indicators. Weights are adapted for Greece: Integrity 15%, Rule of Law 15%, Transparency 20%, Responsiveness 10%, Ethics 25%, Enforcement 15%.

Integrity
15%
Rule of Law
15%
Transparency
20%
Responsiveness
10%
Ethics
25%
Enforcement
15%

Each indicator is scored on [0–1] and accompanied by a documented note. Cross-cutting quality fields (completeness, confidence level, source count, notes on systemic gaps) are stored per politician.

Data Quality & Assurance

Given the Greek data landscape, only ~40–55% of indicators are reliably measurable. To preserve objectivity, we record: (a) completeness_pct, (b) confidence_level (LOW/MED/HIGH), (c) source_count, and (d) notes on systemic gaps. Non-observable indicators are treated as missing-by-design—neither zeroed nor inflated—paired with a confidence penalty.

  • Multi-source triangulation (e.g., Government Gazette, Parliament, ADAE/Supreme Audit, EP/PEGA, official registers).
  • Audit trail with timestamps and per-indicator documentation text.
  • Revisability: all changes retain history and justification.

Scoring Pipeline

  1. Indicator Scaling [0–1]: Binary or continuous (linear or logarithmic) with normalization. Every value is accompanied by a justification note.
  2. Pillar Aggregation: Mean of available indicators per pillar, with quality-aware weighting (e.g., LOW/MED/HIGH weights).
  3. Thematic Composition: Six categories are composed using the predefined weights.
  4. Final PAI: Weighted 0–1 composite. We also publish uncertainty summaries derived from completeness/confidence.

The 24 Pillars

Each pillar comprises specific indicators with definitions, sources, and scaling rules. Where public measurement is not feasible, we treat it as Missing-by-Design—no unfair penalty, but confidence is reduced and transparently disclosed.
P1. Integrity & Corruption Control

Construct. Personal integrity hinges on timely/complete asset declarations, conflict-of-interest (COI) transparency, and absence of formal ethics sanctions. Where statutory systems are partially implemented, we benchmark to what a diligent official could make public and to third-party oversight traces.

Operationalization. Indicators include asset declaration timeliness/completeness, COI disclosure quality, and recorded ethics sanctions. Non-observable sub-measures are coded missing-by-design with confidence penalties; observable events (sanctions) are binary or timed decay if expunged.

Interpretation. High scores denote proactive integrity practices beyond the legal minimum, not merely the absence of convictions.

P2. Rule of Law & Constraints on Power

Construct. Commitment to institutional constraints is reflected in support for independent oversight bodies, compliance with court orders, and adherence to parliamentary procedure.

Operationalization. Voting records on judicial independence may be unavailable; we rely on documented actions supporting bodies (e.g., ADAE, Supreme Audit, EPPO/PEGA), court-order compliance where case-law exists, and Speaker-recorded procedural rulings.

Interpretation. The pillar rewards demonstrable support for checks-and-balances rather than partisan expedience.

P3. Transparency & Open Government

Construct. Openness is captured via proactive disclosure beyond statutory minima, FOI compliance, parliamentary question responsiveness, and meeting/lobby transparency.

Operationalization. Where no formal lobby register exists, we score voluntary meeting disclosures and publication habits; FOI metrics are constrained by the legal regime and statistics availability.

Interpretation. High scores reflect systematic publication beyond compliance, offering reproducible public audit trails.

P4. Responsiveness to Scrutiny

Construct. Responsiveness captures diligence toward parliamentary committees, quality/timeliness of answers, issuance of corrections, and constituency case handling.

Operationalization. Attendance is often unpublished; we complement with answer timeliness proxies, formal errata, and ombudsman-style case handling where available.

Interpretation. The measure distinguishes performative engagement from verifiable, timely, and corrective interactions.

P5. Ethics Norms Adherence

Construct. Ethical conformance includes code-of-conduct violations, gift register completeness, documented recusals on COI, and revolving-door controls.

Operationalization. We code violations and sanctions; gifts are assessed for coverage and granularity; recusal behavior is often untracked; revolving-door is reconstructed from career timelines and cooling-off regimes.

Interpretation. Scores emphasize verifiable, prospective risk controls rather than post-hoc justifications.

P6. Enforcement Outcomes

Construct. Enforcement measures whether rules “bite”: sanctions imposed, corrective actions taken, repeat-offender patterns, and behavior in landmark integrity cases.

Operationalization. We record actual sanctions, remedial steps, recurrence patterns, and conduct in major events (e.g., handling of surveillance scandals) as binary/ordinal indicators with documented sources.

Interpretation. High scores indicate effective, credible accountability — not merely the existence of rules on paper.

P1.1 Asset Declaration Timeliness

Measures on-time filing relative to statutory deadlines and historical patterns; late filings decay score by severity and frequency. Missing official publication is treated as non-observable with confidence penalties, not as zero.

P1.2 Asset Declaration Completeness

Assesses declared scope (assets, liabilities, beneficial interests) and attachment sufficiency. In absence of public attachments, triangulation with credible third-party reports is documented.

P1.3 Conflict-of-Interest Disclosure Quality

Evaluates the presence, specificity, and update cadence of COI statements; explicit recusals improve this score when verifiable.

P1.4 Ethics Sanctions (Recorded)

Binary/ordinal scoring of formal findings and sanctions, with time decay for older events post-rehabilitation windows.

P2.1 Votes on Judicial Independence

Where roll-calls are absent, this is missing-by-design; proxy narratives are documented separately (non-scoring).

P2.2 Support for Oversight Bodies

Actions that resource, defend, or strengthen ADAE/EPPO/PEGA, audit institutions, and Ombudsman; negative actions reduce score.

P2.3 Court-Order Compliance

Tracks compliance with final court decisions; verified non-compliance yields sharp penalties; compliance strengthens Rule-of-Law signal.

P2.4 Parliamentary Procedure Adherence

Uses Speaker/committee records for breaches vs. clean conduct; chronic breaches trend score down.

P3.1 Parliamentary Question Responsiveness

Rates response rates/latency where tracked; where not tracked, coded missing with documentation.

P3.2 Freedom-of-Information Compliance

Assesses FOI responsiveness where a legal/statistical basis exists; otherwise documented as a systemic gap (non-scoring).

P3.3 Meeting / Lobby Transparency

Scores voluntary publication of meetings/contacts; absence of a formal register does not preclude high voluntary transparency.

P3.4 Proactive Disclosure Beyond Minimum

Rewards systematic, structured publication of datasets, calendars, and decisions beyond statutory minima, enabling reproducible audits.

P4.1 Committee Attendance

Where attendance is not published it is missing-by-design; when available, we normalize by expected load and tenure length.

P4.2 Answer Quality & Timeliness

Combines latency windows and content adequacy rubrics; repeated non-answers depress scores more than isolated delays.

P4.3 Corrections / Errata Issued

Formal corrections demonstrate accountability; timely, self-initiated errata score highest, adversarially compelled ones moderately.

P4.4 Constituency Case Handling

Where casework stats exist, we compute closure rates adjusted for complexity; otherwise flagged as non-observable with narrative note.

P5.1 Code-of-Conduct Violations

Indexed severity/frequency over time, with rehabilitation windows; zero indicates clean record within observation window.

P5.2 Gift Register Completeness

Coverage, thresholding, and granularity (donor, value, date); partial systems are scored on best-effort publication fidelity.

P5.3 Recusal Behaviour

Verifiable recusals on COI earn credit; absence of tracking is documented without punitive assumptions.

P5.4 Revolving-Door Controls

Applies to cooling-off compliance and ex-ante reviews; career timelines are reconstructed from career transitions.

P6.1 Sanctions Imposed

Binary/ordinal based on official sanctioning decisions; independent body sanctions carry higher weight than internal admonitions.

P6.2 Corrective Actions Taken

Records remedial actions proportional to breach; timeliness and completeness matter for scoring uplift.

P6.3 Repeat-Offender Status

Recurrence within a rolling window compounds penalties; clean periods attenuate past penalties per defined decay.

P6.4 Landmark-Case Behaviour

Conduct in major integrity events (e.g., high-salience surveillance cases) is coded from verifiable records; neutrality, cooperation, and corrective stance drive scores.

Reproducibility & Objectivity

All measurements carry explicit citations and timestamps. Any revision requires justification; alternative interpretations are logged in the indicator note. The final score ships with uncertainty and completeness summaries, so users know what is measurable—and how reliable it is.
