  • Seeing both sides of the coin may make you slow, conf\used and less confident- mixed emotions. But there are some advantages-

    “Ambivalent individuals’ ability to see all sides of an argument and feel mixed emotions appears to have some benefits. They may be better able to empathize with others’ points of view, for one thing. And when people are able to feel mixed emotions, such as hope and sadness, they tend to have healthier coping strategies, such as when a spouse passes away, according to Dr. Larsen. They may also be more creative because the different emotions lead them to consider different ideas that they might otherwise have dismissed.”

  • “The duo investigated a well-established phenomenon called stereotype threat, where stereotypes fuel themselves in a vicious circle. People exposed to a stereotype become so worried about conforming to them that they end up doing so. As an example, women do more poorly in maths tests if they have previously been reminded of the supposed male superiority in that subject or even, simply, if their gender is highlighted. Likewise, black schoolchildren do worse in intelligence tests if their race is drawn to attention, but they narrow the gap if they sit through an exercise designed to boost their self-worth.
    Many studies have found that stereotype threat can hamper a woman’s performance, knocking her test scores, her chess-playing ability and even her career ambitions. Now, Carr and Steele have found, for the first time, that such threats can also affect a woman’s financial decision-making.”

  • Personal Identity- much more that what our genes map out- the container is not the contained!

    “Well, so far only one connectome is known, that of this tiny worm. Its modest nervous system consists of just 300 neurons. And in the 1970s and ’80s, a team of scientists mapped all 7,000 connections between the neurons. In this diagram, every node is a neuron, and every line is a connection. This is the connectome of the worm C. elegans. Your connectome is far more complex than this, because your brain contains 100 billion neurons and 10,000 times as many connections. There’s a diagram like this for your brain, but there’s no way it would fit on this slide. Your connectome contains one million times more connections than your genome has letters. That’s a lot of information.

    What’s in that information? We don’t know for sure, but there are theories. Since the 19th century, neuroscientists have speculated that maybe your memories — the information that makes you you — maybe your memories are stored in the connections between your brain’s neurons. And perhaps other aspects of your personal identity — maybe your personality and your intellect — maybe they’re also encoded in the connections between your neurons. And so now you can see why I proposed this hypothesis: I am my connectome. I didn’t ask you to chant it because it’s true, I just want you to remember it.”

  • Interesting, may be we should make more holistic use of our brain?-

    “The researchers correlated each patient’s occupation scores with the location of brain tissue loss as determined from brain imaging results. They found that patients with professions rated highly for verbal skills, such as school principals, had greater tissue loss on the right side of the brain, whereas those rated low for verbal skills, such as flight engineers, had greater tissue loss on the left side of the brain. This effect was expressed most clearly in the temporal lobes of the brain.
    “The disease appeared to attack the side of the brain that was the least used in the patient’s professional life,” said Dr. Nathan Spreng, who conducted the study as a psychology graduate student at Baycrest and is now a post doctoral fellow in the Department of Psychology at Harvard University.”

  • Explores the idea of exalting goodness/ or something of that sort. We limit ourselves to praise, in this rationalist time. May be, we feel we have to exalt, glorify by way of emotional need?” It is irrational, except maybe as a sop to our frailty and sense of beauty. And yet Daniel Dennett, after nearly dying, thanked “goodness” for his recovery: the goodness of medicine, of the efforts and concerns of everyone who helped him. …”…I would suspect that there is a distinct human need filled by praise. We want very badly for something to be an unalloyed repository of good. It is not normally credible to conceive oneself as perfect, but we need at least something or someone to be worthy of praise. We want to look upwards, towards goodness and light; we want to be the kind of people who are capable of praise, capable of a reverent and appreciative frame of mind. …

  • “Vipassana meditation aims to change the way we assign affect to mental states, and reverse the damage accumulated from doing so poorly in the past.”—-“I describe a way to understand vipassana meditation (a form of Buddhist meditation) using the concept of affective judgment1. Vipassana aims to break the habit of blindly making affective judgments about mental states, and reverse the damage done by doing so in the past. This habit may be at the root of many problems described on LessWrong, and is likely involved in other mental issues. “
