Shawn Carlson (born 1960) is an Americanphysicist,science writer, and aSTEM educator.

Carlson graduated from U.C. Berkeley with Bachelor of Science degrees in both Applied Mathematics and Physics in 1981.^{[citation needed]} He graduated fromUCLA with a master's degree in physics in 1983, and with a Ph.D. in Nuclear Physics in 1989.^{[citation needed]} As a post doc, Carlson ran theLeuschner Observatory for the Center for Particle Astrophysics at theLawrence Berkeley National Laboratory and was chief observer for the Berkeley Automated Supernovae Search.^[2]

While an undergraduate, Carlson carried out adouble-blind test of astrologers' abilities to extract information about their clients from the apparent positions of celestial objects as seen from the places and times of their clients' births.^[3]

Carlson's experiment involved twenty-eight astrologers who were held in high esteem by their peers.^[4] They agreed to match over 100 natal charts to psychological profiles that were generated by theCalifornia Psychological Inventory (CPI), a standard and well accepted personality test, which the astrologers themselves identified as the scientific instrument that was best aligned with type of information they believed they could divine from their art. The astrologers agreed that the experimental protocol provided a "fair test" of astrology prior to taking part in it.^[4]

The participating astrologers were nominated by theNational Council for Geocosmic Research (NCGR), which acted as the astrological advisors to ensure that the test was fair.^[4] The astrologers came from Europe and the United States.^[3] The astrologers also identified the central proposition of natal astrology to be tested.^[4]

The results were published inNature on December 5, 1985. The study found that astrologers were unable to match natal charts to their corresponding personality tests better than chance. Moreover, astrologers were no more likely to be correct even when they had high confidence that they had made a match correctly. Carlson concluded that the result "clearly refutes the astrological hypothesis".^[4]

Carlson left academia in 1994 and founded theSociety for Amateur Scientists.^[2][5] He contributed to the columns "Science on Society" onThe Humanist from 1990-1992,^{[citation needed]} "The Amateur Scientist" inScientific American from 1995 to 2001,^[2] and "The Citizen Scientist" forMake magazine from 2005 to 2007.^[6] In 2010, he launched LabRats Science Education Program, an organization that organizes activities for and encourages amateur scientists.^[7] He currently serves as Executive Director for the organization.^[7]
