1. A computer implemented method for inferring a probability of a first inference, wherein the first inference comprises an identification of a dangerous individual, wherein the dangerous individual comprises any individual, individuals, or group of individuals that are disturbed, distressed, or mentally ill and that have a likely predisposition to violent behavior, according to a likely determination of a professional of ordinary skill in the art of mental health, assuming that the professional had possession of at least one fact that would be relevant to the professional in making the determination, wherein likely comprises more probable than not, wherein relevant comprises relevance according to accepted standards of those of ordinary skill in the art of mental health, and wherein the computer implemented method comprises: receiving a query at a database regarding a fact, wherein the first inference is absent from the database, wherein the database comprises a plurality of divergent data, wherein the plurality of divergent data includes a plurality of cohort data, wherein each datum of the database is conformed to the dimensions of the database, wherein each datum of the plurality of data has associated metadata and an associated key, wherein the associated metadata comprises data regarding cohorts associated with the corresponding datum, data regarding hierarchies associated with the corresponding datum, data regarding a corresponding source of the datum, and data regarding probabilities associated with integrity, reliability, and importance of each associated datum; establishing the fact as a frame of reference for the query; applying a first set of rules to the query, wherein the first set of rules are determined for the query according to a second set of rules, wherein the first set of rules determine how the plurality of data are to be compared to the fact, and wherein the first set of rules determine a search space for the query; executing the query to create the probability of the first inference, wherein the probability of the first inference is determined from comparing the plurality of data according to the first set of rules; and storing the probability of the first inference.
