When 68-year-old mrs. blake had a flat tire on a fairly isolated highway, she received from a passerby in less than 10 minutes. one year later, when she had a flat tire on a busy freeway, an hour elapsed before someone finally stopped to offer assistance. mrs. blake’s experience best illustrates
a) the fundamental attribution error.
b) the mere exposure effect.
c) group polarization.
d) the bystander effect.

Recall that in one condition of the experiment conducted by stasser and titus (1985) about student council president candidates, all group members had access to the same information, and that in another condition, members had unique information that other group members didn't know. in the second (unshared information) condition, the group made a worse decision than in the first (shared information) condition. this occurred because groups seldom can agree on who is most expert. focus discussion on the information that all members know. often ignore dissenting opinions. avoid differences of opinion, given conformity pressures.
