The project is detailed in the contract as a seven
step process — with Kogan's company, GSR, generating an initial seed sample (though it does not specify how large this is here) using «online panels»; analyzing this seed training data using its own «psychometric inventories» to try to determine personality categories; the next
step is Kogan's personality quiz app being deployed on Facebook to gather the full dataset from respondents and also to scrape a subset
of data from their Facebook friends (here it notes: «upon consent
of the respondent, the GS Technology scrapes and retains the respondent's Facebook profile and a quantity
of data on that respondent's Facebook friends»);
step 4 involves the psychometric data from the seed sample, plus the Facebook profile data and friend data all being run through proprietary modeling
algorithms — which the contract specifies are based on using Facebook likes to predict personality scores, with the stated aim
of predicting the «psychological, dispositional and / or attitudinal facets
of each Facebook record»; this then generates a series
of scores per Facebook profile;
step 6 is to match these psychometrically scored profiles with voter record data held by SCL — with the goal
of matching (and thus scoring) at least 2M voter records for targeting voters across the 11 states; the final
step is for matched records to be returned to SCL, which would then be in a position to craft messages to voters based on their modeled psychometric scores.
