Dr. Pieternel Dijkstra had been publishing outstanding papers for the Online Dating Industry, but C-Level executives had been ignoring her research since years.
"Perceptions of Ideal and Former Partners' Personality and Similarity"
Pieternel Dijkstra / Dick P. H. Barelds / University of Groningen, The Netherlands
she had written "our study showed that individuals did not rate similarity in personality as very important when seeking a mate. Our findings may help understand why so many relationships end in divorce due to mismatches in personality."
"The present study's results, as well as the results found in previous studies (e.g., Eastwick & Finkel, 2008), may be used to educate people, especially singles, about what really matters in long-term relationships, for instance, similarity in personality, instead of complementarity."
Dr. Pieternel Dijkstra had also published the paper "Partner Preferences of the Intellectually Gifted"
".... dissimilarities in, for instance, age, values, interests, and personality are usually mentioned as the main reason for relationship breakup (e.g., Amato & Previti, 2003). For instance, in The Netherlands, where the present study was conducted, almost 40% of the divorcees report mismatches in personalities as the major cause of their break-up (De Graaf, 2006). Based on the similarity-attraction hypothesis we therefore expected the intellectually gifted, compared with other people, to more strongly value a potential partner’s high intelligence."
The tests used by Intelligent Elite (IQElite), Brainiac Dating, IQ Gorgeous and the others DO NOT meet IRT, they are all ... rubbish because IQ tests are ability tests, answers could be Right or Wrong, so the questions should be sorted in increasing difficulty forming a Rasch Hierarchy. Those IQ tests sould be constructed using Modern Test Theory / Item Response Theory (IRT)..

*personality measured with a normative test.
*similarity: there are different ways to calculate similarity, it depends on how mathematically is defined.
