Self-fulfilling
Prophecy
Self-fulfilling prophecy refers to the phenomenon in which a person who
believes in a prophecy learns to act in accordance with the prophecy,
thereby bringing the prophecy to being. An example that psychologists
have studied is astrology (Glick & Snyder, 1986; Eysenck and Nias,
1982; Snyder, 1984). If a person’s original personality and his/her sign
matches, that tendency becomes stronger. Even if the personality and the
sign do not initially match, the personality moves toward what has been
indicated. In Japan, South Korea, and Taiwan, roughly half of the people
feel the relationship between blood type and personality is
legitimate (Cho, Suh & Ro, 2005;
Kamise & Matsui, 1994 & 1995; Sato & Watanabe, 1992; Wu, Lindsted &
Lee, 2005; Yamaoka, 2009). Logically, the self-fulfilling findings among
astrology suggest that one’s personality would change in a direction
that fits relevant as personality description – of which shown by blood
type.
