v2.4 release note

From rigorous methodology to flexible execution, built for Big Five research.

From versioned IPIP-NEO-120 scoring to reproducible exports and transparent QC flags, b5lab helps research teams move from collection to analysis with confidence.

Built for rigorous academic deployment

From raw responses to analysis-ready evidence

  • 1
    Versioned IPIP-NEO-120 scoring
    Each completed session stores scoring version, domain totals, and facet totals for citation-ready traceability.
  • 2
    Transparent quality control flags
    Speeding, straightlining, invariance, and missingness are computed at completion to support explicit inclusion criteria.
  • 3
    Reproducible export package
    Exports include codebook metadata, QC policy context, and exclusion reasons so methods teams can reproduce decisions.

Scientific evidence layer

Methodological rigor built into the product surface

Rigor is implemented as product behavior: versioned scoring, explicit QC signals, and exports that preserve analytical context.

Standardized IPIP-NEO-120 scoring pipeline

Participant completion automatically computes domain and facet totals with explicit scoring version tags for downstream citation and traceability.

Built-in data quality screening

Completed sessions include automated speeding, straightlining, invariance, and missingness checks to support transparent exclusion logic.

Reproducible exports for analysis teams

Exports carry scoring versions, QC thresholds, and item metadata so statistics and methods teams can reproduce decisions consistently.

Analysis-ready inclusion recommendations

Rows include `include_in_analysis` and explicit exclusion reasons, reducing manual preprocessing effort before modeling.

02

Research workflow flexibility

Design collection workflows without sacrificing methodological control

Combine recruitment flexibility, entitlement guardrails, and role boundaries in one workspace while keeping scientific outputs consistent.

Entitlement-aware study operations

Session starts, access-code generation, and exports are guarded by plan and credit checks to prevent silent operational drift.

Flexible recruitment modes

Run anonymous studies for broad intake or tokenized studies when cohort eligibility and controlled distribution are required.

What research teams get

Capabilities that protect data quality and delivery speed

Domain-aware onboarding controls

Institutional domains can self-serve workspace setup while claimed domains route members through moderated join requests.

Predictable entitlement guardrails

Credits, seats, and lab limits stay visible so teams can plan capacity before research operations are blocked.

Role-specific governance controls

Separate billing authority and study operations using institution admin, billing admin, viewer, and lab-level roles.

Anonymous and tokenized participant access

Manage controlled cohorts with access-code generation, claim, revoke, and expiry workflows in the same product surface.

Reproducible exports with metadata context

Export JSON and CSV with item codebook, scoring version, facet/domain totals, QC policy, and exclusion reasons.

Quality and trait analytics workspace

Explore quality breakdowns, trait distributions, demographics, and session trends with study-scoped filtering.

04

Research execution flow

Three steps from setup to defensible analysis

01

Configure study and recruitment policy

Create an IPIP-NEO-120 study, choose locale, and select anonymous or tokenized participant recruitment.

02

Collect sessions with explicit QC checks

Completion computes domain/facet scoring plus speeding, straightlining, invariance, and missingness QC flags.

03

Export reproducible analysis package

Download JSON/CSV exports with scoring version, QC policy metadata, exclusion reasons, and multilingual codebook context.
