How the science works

How the science works

Personality science is not new. Across three decades of peer-reviewed research, the traits behind reliability and follow-through have predicted job performance in every occupation studied. What is new is an assessment fast enough that every candidate actually completes it.

THE FRAME

Resumes and skills describe the past. Hiring is a bet on potential: what someone will do next. Personality fit is the best available marker of how someone will actually operate in the role going forward.

Built on the Big Five

The Big Five is the most validated framework in personality psychology. Staffcloud presents each factor in plain work language, with neutral poles and no “good” or “bad” ends.

OPENNESS

Exploratory Mindset

Preference for novelty, experimentation, and abstract problem-solving versus proven, practical methods.

Experimental ↔ Practical

CONSCIENTIOUSNESS

Work Style

Preference for structure, planning, and follow-through versus adaptability and improvisation.

Structured ↔ Flexible

EXTRAVERSION

Social Energy

Where someone draws energy — outward collaboration and visibility versus focused, independent work.

Reserved ↔ Outgoing

AGREEABLENESS

Interpersonal Style

Default posture in disagreement — accommodating and consensus-seeking versus firm and challenge-ready.

Accommodating ↔ Firm

EMOTIONAL STABILITY

Emotional Style

How someone responds under pressure and setback — reactive and sensitive to stress versus composed and even-keeled.

Reactive ↔ Composed

A Better Assessment for Real-World Hiring

Traditional personality questionnaires force a trade-off: rigorous instruments candidates abandon, or fun quizzes with no science. myTrudy ends that trade-off.

Science that holds up. In a head-to-head test, myTrudy matched the gold-standard academic instrument’s predictive power for overall job performance - using 35 quick images instead of 50 written statements.⁴

Identifies team players. Predict who goes above and beyond - including helping teammates, taking initiative, contributing past the job description.⁵

Real psychometrics behind every image. Images selected empirically through item response theory, factor analysis, and reliability evidence, then confirmed on an independent holdout sample.⁶

Described as "effortless" by candidates. 93% of candidates complete the assessment and do so in under three minutes – producing complete, honest data from your whole pipeline, not just the patient few.

Built for compliance. Evaluated for adverse impact across gender, age, and ethnicity, and scored on whole-person profiles, never single-trait pass/fail cutoffs.⁷

DATA & REFERENCES

1. Barrick & Mount (1991), Personnel Psychology, 44(1); Sackett et al. (2021), Journal of Applied Psychology, 106(12).

2. myTrudy median completion time under 3 minutes (35 forced-choice image items); traditional 50-item Big Five questionnaires typically require 7–10 minutes.

3. 5 independent validation studies of employed U.S. adults (N≅1,000/study). Version 5: N = 997 (ages 18–76, 77% employed full-time) after attention-check screening.

4. Multiple correlation with overall work performance: myTrudy R = .51 vs. IPIP-50 R = .65 (78% retained), N = 997; outcomes measured by the Individual Work Performance Questionnaire (Koopmans et al., 2014).

5. Contextual-performance ranking concordance: myTrudy .67 vs. .70 for the 50-item IPIP benchmark (Goldberg, 1992) on the same N = 997 sample — within 3 percentage points, from 35 image choices instead of 50 written statements.

6. Final 35 items selected from a 46-item pool via item response theory, factor analysis, and reliability evidence (exploratory n = 498); structure confirmed via CFA on an independent holdout (n = 499). Same-trait convergence with the IPIP-50: .68 (E), .55 (C), .54 (A), .49 (N); four of five traits correlated most strongly with their intended counterpart.

7. Adverse-impact evaluation aligns with NYC Local Law 144 methodology: adverse-impact ratios, effect sizes, and the 2SD rule across gender, age, and ethnicity. Subgroup differences on the image format mirror those observed on the established written benchmark.
