To optimise the chances of finding even remote relationships between date of birth and individual differences in personality and intelligence we further applied two different strategies. The first one was based on the common chronological concept of time (e.g. month of birth and season of birth). The second strategy was based on the (pseudo-scientific) concept of astrology (e.g. Sun Signs, The Elements, and astrological gender), as discussed in the book Astrology: Science or superstition? by Eysenck and Nias (1982).

This underlies the "Barnum effect". Named after the 19th-century showman Phineas T. Barnum, whose circus act provided "a little something for everyone", it refers to the idea that people believe a statement about their personality that is vague or trivial if they think that it derives from some systematic procedure tailored especially for them (Dickson & Kelly, 1985; Furnham & Schofield, 1987; Rogers & Soule, 2009; Wyman & Vyse, 2008). For example, the more birth detail is used in an astrological prediction or horoscope, the more credulous people tend to be (Furnham, 1991). However, confirmation bias means that people do not tend to pay attention to other information that might disconfirm the credibility of the predictions.
The Barnum effect is a robust phenomenon, having been demonstrated in clinical, occupational, educational, forensic, and military settings as well as numerous ostensibly paranormal contexts (Dickson & Kelly, 1985; Furnham & Schofield, 1987; Snyder, Shenkel & Lowery, 1977; Thiriart, 1991). In the first Barnum study, Forer (1949) administered, astrological believers deemed a Barnum profile supposedly derived from astrology was a better description of their own personality than did astrological skeptics. This was true regardless of the respondent's ethnicity or apparent profile source. This reinforces still further the view that individuals who endorse astrological beliefs are prone to judging the legitimacy and usefulness of horoscopes according to their a priori expectations.
The effect was replicated several times (Eysenck & Nias 1981,1982; Fichten & Sunerton, 1983; Jackson, 1979; Kelly, 1982; Smithers and Cooper, 1978), even if no reference to astrology was made until the debriefing of the subjects (Hamilton, 1995; Van Rooij, 1994, 1999), or if the data were gathered originally for a purpose that has nothing to do with astrology (Clarke, Gabriels, and Barnes, 1996; Van Rooij, Brak, & Commandeur, 1988), but the effect is stronger when a cue is given to the subjects that the study is about astrology (Van Rooij 1994). Early evidence for sun-sign derived self-attribution effects has already been reported by Silverman (1971) and Delaney & Woodyard (1974). In studies with subjects unfamiliar with the meaning of the astrological sun-sign symbolism, no effect was observed (Fourie, 1984; Jackson & Fiebert, 1980; Kanekar & Mukherjee, 1972; Mohan, Bhandari, & Meena, 1982; Mohan and Gulati, 1986; Saklofske, Kelly, & McKerracher, 1982; Silverman & Whitmer, 1974; Veno & Pamment, 1979).
About three-fourths of Americans hold at least one pseudoscientific belief; i.e., they believed in at least 1 of the 10 survey items[29]"..." Those 10 items were extrasensory perception (ESP), that houses can be haunted, ghosts/that spirits of dead people can come back in certain places/situations, telepathy/communication between minds without using traditional senses, clairvoyance/the power of the mind to know the past and predict the future, astrology/that the position of the stars and planets can affect people's lives, that people can communicate mentally with someone who has died, witches, reincarnation/the rebirth of the soul in a new body after death, and channeling/allowing a "spirit-being" to temporarily assume control of a body.
