Zick Rubin

Isaac Michael "Zick" Rubin (born 1944) is an American social psychologist, lawyer, and author. He is "widely credited as the author of the first empirical measurement of love," for his work distinguishing feelings of like from feelings of love via Rubin's Scales of Liking and Loving. ''Science Progress'' stated, "The major breakthrough in research on love came from the pioneer psychometric work of Zick Rubin."

He has also published on disclosing to consequential strangers. According to ''The Cambridge Handbook of Personal Relationships,'' Rubin "conducted influential early studies on disclosure reciprocity in naturalistic settings, such as in airport departure lounges and at bus stops." His work also examined the development of friendship among toddlers. Provided by Wikipedia
