Health officials in Nigeria are celebrating an impressive milestone: The country has gone one year without a single case of polio. The world is now one step closer to making polio the second human infectious disease – after smallpox – to be eradicated with an effective vaccination campaign.
Nigeria is now on the brink of eradicating the paralyzing disease, which predominately affects children under five. Polio (poliomyelitis) is a highly infectious disease, which invades the nervous system and can at times paralyze a victim in a matter of hours. The disease is caused by a virus that spreads through unhygienic environments. One in 200 infections leads to irreversible paralysis and 5% to 10% among those paralyzed die.
There are only three countries where polio remains endemic – Afghanistan, Nigeria and Pakistan. If no cases are reported in the following weeks and the World Health Organization(WHO) confirms previously affected areas are free of the virus, Nigeria is expected to be removed from the list of countries where polio is endemic.
What can we learn about racism from rodents? Sympathy and Optimism?
Anytime you’re talking about the cultural domain, it certainly can be advantageous to pass as black. In many ways, particularly when you’re talking about the discourse around authenticity in jazz, the most authentic jazz players had to be black. And so if you’re a white jazz player who believes that—and that’s the paradoxical irony of being a white jazz musician, is that many of them were quite traditional in their sense that it’s an authentically black music, and so a black person must play it—but what do I do, because I’m not black?
This is probably too long and nerdy for most. It is nonetheless considered by many the seminal work on this topic. It’s also one of my favorite scientific papers!
Evolution and Self-Deception
the ﬁrst corollary to our central proposal is that by deceiving themselves, people are able to avoid the cognitive costs of consciously mediated deception.
Thus, the second corollary to our central proposal is that by deceiving themselves, people can reduce retribution if their deception of others is discovered.
People not only self-enhance the world over, but the average person appears to be convinced that he or she is better than average (Alicke & Sedikides 2009). Most of the research on self-enhancement does not allow one to assess whether these aggrandizing tales are self-deceptive or only intended to be other-deceptive, but some of the variables used in this research support the idea that people believe their own self-enhancing stories. For example, in a pair of clever experiments Epley and Whitchurch (2008) photographed participants and then morphed these photographs to varying degrees with highly attractive or highly unattractive photos of samesex individuals. Epley and Whitchurch then presented participants with these morphed or unaltered photos of themselves under different circumstances. In one experiment participants were asked to identify their actual photo in an array of actual and morphed photographs of themselves. Participants were more likely to choose their photo morphed 10% with the more attractive image than either their actual photo or their photo morphed with the unattractive image. This effect emerged to a similar degree with a photo of a close friend, but it did not emerge with a photo of a relative stranger. Because people often perceive their close friends in an overly positive light (Kenny & Kashy 1994), these ﬁndings suggest that people do not have a general bias to perceive people as more attractive than they really are, but rather a speciﬁc bias with regard to themselves and close others.
our second proposal is that by deceiving themselves about their own positive qualities and the negative qualities of others, people are able to display greater conﬁdence than they might otherwise feel, thereby enabling them to advance socially and materially.
There are a variety of dissociations between seemingly continuous mental processes that ensure that the mental processes that are the target of self-deception do not have access to the same information as the mental processes deceiving the self. For our purposes, these dissociations can be divided into three (overlapping) types: implicit versus explicit memory, implicit versus explicit attitudes, and automatic versus controlled processes. These mental dualisms do not themselves involve selfdeception, but each of them plays an important role in enabling self-deception. By causing neurologically intact individuals to split some aspects of their self off from others, these dissociations ensure that people have limited conscious access to the contents of their own mind and to the motives that drive their behavior (cf.Nisbett & Wilson 1977). In this manner the mind circumvents the seeming paradox of being both deceiver and deceived.
Additionally, social sharing of information can lead to selective forgetting of information that is not discussed (Coman et al. 2009; Cuc et al. 2007) and social conﬁrmation of inaccurate information can exacerbate the false memory effect (Zaragoza et al. 2001). These social effects raise the possibility that when people collaborate in their efforts to deceive others, they might also increase the likelihood that they deceive themselves. Thus, one consequence of retrieving, rehearsing, and telling lies is that people may eventually recollect those lies as if they actually happened, while still maintaining the accurate sequence of events in a less consciously accessible form in memory (Chrobak & Zaragoza 2008; Drivdahl et al. 2009; McCloskey & Zaragoza 1985).
Therefore, our third proposal is that the dissociation between conscious and unconscious memories combines with retrieval-induced forgetting and difﬁculties distinguishing false memories to enable self-deception by facilitating the presence of deceptive information in conscious memory while retaining accurate information in unconscious memory.
An important question that must be addressed with regard to all of these instances of biased processing is whether they reﬂect self-deception or some other source of bias. Two manipulations have proven useful in addressing this issue: self-afﬁrmation (Sherman & Cohen 2006; Steele 1988) and cognitive load (e.g., Valdesolo & DeSteno 2008). When people are self-afﬁrmed, they are typically reminded of their important values (e.g., their artistic, humanist, or scientiﬁc orientation) or prior positive behaviors (e.g., their kindness to others). By reﬂecting on their important values or past positive behaviors, people are
… when self-deception is in service of social advancement via self-enhancement, self-afﬁrmation should attenuate or eliminate the self-deception because the afﬁrmation itself satisﬁes the enhancement goal. In contrast, when people self-deceive to facilitate their deception of others on a particular issue, self-afﬁration should have no effect. Here the goal of the self-deception is not to make the self seem more efﬁcacious or moral, but rather to convince another individual of a speciﬁc ﬁcation that the self-deceiver wishes to promulgate. Self-afﬁrmation is irrelevant to this goal.
