The affect heuristic is how an overall feeling of goodness or badness contributes to many other judgments, whether it’s logical or not, whether you’re aware of it or not. Subjects told about the benefits of nuclear power are likely to rate it as having fewer risks; stock analysts rating unfamiliar stocks judge them as generally good or generally bad—low risk and high returns, or high risk and low returns—in defiance of ordinary economic theory, which says that risk and return should correlate positively.
The halo effect is the manifestation of the affect heuristic in social psychology. Robert Cialdini summarizes:1
Research has shown that we automatically assign to good-looking individuals such favorable traits as talent, kindness, honesty, and intelligence (for a review of this evidence, see Eagly, Ashmore, Makhijani, and Longo, 1991). Furthermore, we make these judgments without being aware that physical attractiveness plays a role in the process. Some consequences of this unconscious assumption that “good-looking equals good” scare me. For example, a study of the 1974 Canadian federal elections found that attractive candidates received more than two and a half times as many votes as unattractive candidates (Efran and Patterson, 1976). Despite such evidence of favoritism toward handsome politicians, follow-up research demonstrated that voters did not realize their bias. In fact, 73 percent of Canadian voters surveyed denied in the strongest possible terms that their votes had been influenced by physical appearance; only 14 percent even allowed for the possibility of such influence (Efran and Patterson, 1976). Voters can deny the impact of attractiveness on electability all they want, but evidence has continued to confirm its troubling presence (Budesheim and DePaola, 1994).
A similar effect has been found in hiring situations. In one study, good grooming of applicants in a simulated employment interview accounted for more favorable hiring decisions than did job qualifications—this, even though the interviewers claimed that appearance played a small role in their choices (Mack and Rainey, 1990). The advantage given to attractive workers extends past hiring day to payday. Economists examining US and Canadian samples have found that attractive individuals get paid an average of 12–14 percent more than their unattractive coworkers (Hamermesh and Biddle, 1994).
Equally unsettling research indicates that our judicial process is similarly susceptible to the influences of body dimensions and bone structure. It now appears that good-looking people are likely to receive highly favorable treatment in the legal system (see Castellow, Wuensch, and Moore, 1991; and Downs and Lyons, 1990, for reviews). For example, in a Pennsylvania study (Stewart, 1980), researchers rated the physical attractiveness of 74 separate male defendants at the start of their criminal trials. When, much later, the researchers checked court records for the results of these cases, they found that the handsome men had received significantly lighter sentences. In fact, attractive defendants were twice as likely to avoid jail as unattractive defendants. In another study—this one on the damages awarded in a staged negligence trial—a defendant who was better looking than his victim was assessed an average amount of $5,623; but when the victim was the more attractive of the two, the average compensation was $10,051. What’s more, both male and female jurors exhibited the attractiveness-based favoritism (Kulka and Kessler, 1978).
Other experiments have demonstrated that attractive people are more likely to obtain help when in need (Benson, Karabenic, and Lerner, 1976) and are more persuasive in changing the opinions of an audience (Chaiken, 1979) . . .
The influence of attractiveness on ratings of intelligence, honesty, or kindness is a clear example of bias—especially when you judge these other qualities based on fixed text—because we wouldn’t expect judgments of honesty and attractiveness to conflate for any legitimate reason. On the other hand, how much of my perceived intelligence is due to my honesty? How much of my perceived honesty is due to my intelligence? Finding the truth, and saying the truth, are not as widely separated in nature as looking pretty and looking smart . . .
But these studies on the halo effect of attractiveness should make us suspicious that there may be a similar halo effect for kindness, or intelligence. Let’s say that you know someone who not only seems very intelligent, but also honest, altruistic, kindly, and serene. You should be suspicious that some of these perceived characteristics are influencing your perception of the others. Maybe the person is genuinely intelligent, honest, and altruistic, but not all that kindly or serene. You should be suspicious if the people you know seem to separate too cleanly into devils and angels.
And—I know you don’t think you have to do it, but maybe you should—be just a little more skeptical of the more attractive political candidates.

As Different says, but in regard to connections between perceived intelligence, and perceived honesty, to pick two particularly useful examples - the usefulness of either quality, in regard to your interactions with the individual, are dependent upon both. I/e, it isn't a great idea to trust what a not-too-bright individual tells you, even if he or she has never told a lie in their life, for the simple reason that they may not have the faculty to evaluate their statements. And the reverse might be true - particularly bright individuals may not be good candidates for trust, particularly on important issues, because they have great faculty for making value judgments about when it is most profitable to lie. Individuals at either extremes may not be good candidates for trust.
I had a long discussion with my brother on precisely the issue of attractiveness - in regard to banks. Banks are great examples because they spend immense quantities of money making themselves look respectable. So - would you trust your money to a bank that was going to spend some of it making itself look good? Or would you trust your money to a bank that doesn't care how it looks? A bank that cares about its reputation enough to spend massive amounts of money maintaining it isn't going to sacrifice that by stealing your relatively small sum - it is the better choice, presuming on the rationality of the bank. An individual who goes to great lengths to APPEAR competent is going to try to BE competent - someone who doesn't care whether or not they appear competent do not care whether you think they are competent, and hence, may not make an effort to be more competent as relates to you and your business. The better-groomed candidate, other things being equal, is the better choice, presuming upon that individual's rationality. (Particularly since the issue is reinforcing - clients and customers, after all, are making the same judgments.)
An individual who makes an effort to appear more attractive likely has a reason for doing so - they may care what other people think of them (which suggests they'll be nicer, when somebody is watching, at least), they may want to appear more competent (which suggests they'll be better at other things they do, presuming they follow similar levels of investment), and, presuming they DO have rational reasons for taking care of their appearance, they may simply be smarter than your average person. Naturally good looking people may be getting the benefits of biases we develop based on those who acquire appearances by effort - and may get points for honesty, as well, because they aren't attempting to "lie" about their appearance. (Which would be interesting, because it would mean naturally good-looking individuals gain more benefits than those who provided much of the bias incentive to begin with.)
Just some thoughts.
This goes to the saying “dress for the job you want - not the one you have” which many seem to misunderstand as a show for others when in fact the origin is based on the hypothesis that we’re constantly influenced by what we do & can actually project ourselves into a better situation by believing it to be possible.
The bank analogy brings to mind Apple - the brand: your privacy the most important thing to them. Therefore, although we have no way of knowing if thats actually true (as we’re all VERY aware of PR-based-branding ploys these days) we still buy into it because they’re much more likely to avoid tarnishing that brand by faking privacy concern than another brand who doesn’t pretend to care.
