    I found this law very interesting. It also reminds me of the TedTalk we had during advisory on procrastination. Being busy and being busy and efficient is completely different. I have a personally experience that agree on this law. Last week, my days were completely filled with cross-country practice, musical rehearsal, and school work, so everyday I sleep around eleven o'clock. This week, I suddenly have a lot more time as the cross-country season ends and the musical is over, but I still go to bed at eleven o'clock and fill my time still not enough for me. I was busy this week but obviously, my efficiency is much lower than last week. --Sissi (11/18/2016)

    I found this law very interesting because it is related to our topic of our lack of ability to deal with probabilities. We always tends to notice the bad things and rare things that happen to us and we named it coincidence. However, by math, coincidence is not only limited to things that rarely happen; it should also include things that has a high probability to happen. In the reading we did on Lesson Five, it mentions that we tend to think the cluster is not random, so we only find patterns between rarely happened things. For example, the death of two America presidents Lincoln and Kennedy. But what about the presidents who make through their presidency alive? Is it be a coincidence that they all live through their presidency? --Sissi (11/18/2016)

  • The brain has many interacting pathways and loops that create expectations with different probabilities from our previous experiences.

    I found this article very interesting because it explains some aspects of how our expectation can influence our perception. In this article, language is also mentioned that different vocabulary can alter our perception. I think this can be related to the definition of words we talked about recently. I think this article suggests that the definition of a word is the result of our expectation as we often define things differently in our favor if no clear definition is stated. This relationship can also be reversed as we use definitions to describe and organize our expectation. --Sissi (11/16/2016)

  • scary movies don’t actually activate fear responses in the amygdala at all. Instead, it was other parts of the brain that were firing – the visual cortex – the part of the brain responsible for processing visual information, the insular cortex- self awareness, the thalamus -the relay switch between brain hemispheres, and the dorsal-medial prefrontal cortex – the part of the brain associated with planning, attention, and problem solving.

    I found this very interesting as it went deep into the psychology behind the horror movies. It's especially astonishing for me to see that horror movies don't actually activate fear responses, instead they stimulate the prefrontal cortex of our brain. Also, this article provides a lot of possibilities why we are so attracted to horror movies. I think this can be related to our perceptions and logic of survival since horror movie can help us return to the most primitive state(trembling in the woods) feel the impulse of wild. --Sissi (11/14/2016)

shared by sissij on 13 Nov 16 - No Cached
  • Russell's paradox is based on examples like this: Consider a group of barbers who shave only those men who do not shave themselves. Suppose there is a barber in this collection who does not shave himself; then by the definition of the collection, he must shave himself. But no barber in the collection can shave himself.

The formal language contains symbols such as e to express "is a member of," = for equality and to denote the set with no elements.
  • sissij on 13 Nov 16
     
    I found this very interesting because it shows that even in math, there can be illogic paradox. There is no perfect logic. I think this paradox is a circular logic because the premise and assumption is used in the argument. Also, the definition and limitation of "those men" is too vague. I think to make this premise valid, we need to state that barbers are not in the reference of the term "those men" in the premise. --Sissi (11/12/2016)

    I found it very interesting that although there is a stereotype that women drive poorly, men actually cause more accidents in researches. I very agree with the author because he make the term "better" clear in the passage, which most other claims mentioned vaguely. In his writing, "better" has two meanings: how safe one drives and how well one drives. I think looking at the problem through the two very different meaning of "better" can lead to very different conclusions. I think that's why different article held opposite views on this issue. They don't speak in the same language; they are speaking of different "better"s. --Sissi (11/10/2016)

  • I don’t fault Silver for his caution. It’s honest. What it really says is he doesn’t know with much confidence what’s going to happen
  • That’s because there’s a lot of human caprice and whim in electoral behavior that can’t always be explained or predicted with scientific precision. Politics ain’t moneyball. Good-quality polls give an accurate sense of where a political race is at a point in time, but they don’t predict the future.

  • In his hedged forecasts this time, Silver appears to be acknowledging that polling and historical patterns don’t always capture what John Maynard Keynes, in his classic 1936 economic General Theory, described as “animal spirits.”
  • There is, Keynes wrote, “the instability due to the characteristic of human nature that a large proportion of our positive activities depend on spontaneous optimism rather than on a mathematical expectation, whether moral or hedonistic or economic. Most, probably, of our decisions to do something positive, the full consequences of which will be drawn out over many days to come, can only be taken as a result of animal spirits — of a spontaneous urge to action rather than inaction, and not as the outcome of a weighted average of quantitative benefits multiplied by quantitative probabilities.”

shared by kortanekev on 06 Nov 16 - No Cached
  • it's important to define and describe dehumanization, because it's what opens the door for cruelty and genocide.
  • it can be helpful to understand what it is that allows human beings "to overcome the very deep and natural inhibitions they have against treating other people like game animals or vermin or dangerous predators."
  • Mostly, they were seen as "soulless animals." And that dramatic dehumanization made it possible for great atrocities to take place.
  • kortanekev on 06 Nov 16
     
    The use of dehumanizing labels has allowed for the mind to perceive the world in vast oversimplifications -- in recognizing every member of a group as exhibiting certain socially manufactured characteristics  -- and to use this to rationalize one's treatment towards a certain group. Language in this way (through mental short cuts and deep rooted prejudice) has posed the greatest threat to human rights, abuse of power, and their lasting effects on our culture today.

  • Brain maturation during adolescence (ages 10–24 years) could be governed by several factors, as illustrated in Figure 1. It may be influenced by heredity and environment, prenatal and postnatal insult, nutritional status, sleep patterns, pharmacotherapy, and surgical interventions during early childhood.
