OVERVIEW Specialize in
  1. Psychomentrics
  2. Judgement Audits
  3. Modeling Audits
  4. Foundational Psych-Social Demographic Analysis
Specifically, Psychometrics, are personality inventories that can be used in targeted marketing to change client behaviour. Judgement Audits use simulations to analyze reliability and validity of decisions-makers. This saves the organization money and/or ensures client fairness. Modeling Audits look at variable validity, to measure truthfullness of model representation.

ABOUT PSYCHOLOGICAL TRAIT INVENTORY SCALES
Trait Analysis: The Big 5 Personality Inventory
The science behind creation of the 'Big 5 Personality Inventory'.
Exploring the personality trait, "Openness to Experience".
  • Modeling the 'Openness to Experience' Trait (2023-2024)
  • Let's apply the personality inventory, to further test the delineation of the Big 5 categories. We look at one of the personality traits in the dataset (openness to experience), and see how the other traits compare to it.
  • Procedures: logical regression / decision tree / knn / random forest
Compare Traits to Demographics
Comparing personality traits to socio-economic information from geographic regions.
  • Analysis of 4 Psychological Regions of the United States (2023-2024)
  • Now let's get real. Let's compare some regional demographic information to psychological profiles of different regions that have been collected from previous studies.
  • Procedures: contingencies / correlations / descriptives / frequencies / one factor ANOVA / linear & quantile regressions / hierarchical clustering

HEXACO (big 6)
  • "Big Five" is a trait analysis tool used with big data for marketing and influence platforms. HEXACO adds another dimension to describe our traits. This dimension checks a person's motive to lie. This successfully addresses the weakest part of the original Big Five Scale.
