The majority of online love tests are not accurate because they are not research-based or do not fall under any psychological standards. Love tests that are not accurate tend to appear on websites such as Buzzfeed or Facebook.
One rather accurate love test was written by University of Maryland psychologist Sandra Langeslag. Her quiz defined the symptoms that accompany love. Langeslag based her questionnaire on research into long-term relationships and marriage. Therefore, her quiz more accurately measures whether a couple is truly in love.
Compatibility and chemistry quizzes from the leading dating websites such as eHarmony and Match.com are also incredibly accurate. These companies use questionnaires designed by professionals who study human behavior, marriage and the chemistry between those in love.
