Thinking, fast and slow[i]

Basically we have 6 big ideas that can help us live better.
Big idea 1 is to realize that we have 2 ways of thinking: system 1, fast and automatic and system 2, slow and logical. Sometimes we should choose one or the other but we need to avoid swapping them.
Big idea 2 is the anchoring. Sometimes we need to figure out an anchor, a reference to lead us to make a decision. Also we should avoid anchors that are not real and this can help us to best guess.
Big idea 3 is the science of availability. We need to pay attention to the possibility of something happen to us or not and avoid suffering about something that has no chance at all to happen. This means we need to avoid seeing the mainstream media.
Big idea 4 is about loss aversion. In a situation we need to choose between things that will be good in a way and negative in another, we should argue using the negative way to convince the other person. You would prefer to make a decision avoiding something negative.
Big idea 5 is the framing. The way we see a picture can change our conclusion. We can see the same picture in different angles and this can result in different effects. Therefore, try to see at least twice!
Finally, the big idea 6 is sunk cost fallacy. We should avoid base our current decision in one thing we did in the past, it doesn't matter if we are going to lose money.
So, these big ideas are ideas to guide our life and must be used to live better and to make the best choices.

Free will and determinism*

          According to SoL (School of Life), the debate between free will and determinism has been crossing the Philosophy History since the beginning until our time reaching even the neuroscientists. It concerns about whether the human being is able to dominate their actions by themselves or they are determined by forces beyond their control, like fate and politics. SoL argues that the long running arguments in favor or against both sides are not conclusive because they are based on objective variables when they should be thought as what is relevant to me (to me… to me?). Also, they vary from person to person guided by two psychological aspects: defeatism and aspiration.           Does the course of our life belong to the others, like our parents, bosses and so on or can we change our life and our relationships based on our strenght and free will? The second should be even better but more difficult, of course. So moving far from the old and objective discussion and changing the para

The soul is just a function*

Putman talks about the contribution of Computer Science to Philosophy of Mind in terms of thinking the mind as a kind of function rather than physical or chemistry. He says that the rise of computers could result in everything being explained in terms of machines but the paradox is that it didn´t contribute for this kind of reductionism . Generally, according to Putman, when we work with computer we think in its programs, instructions, rules, etc., and we ignore the hardware. Ironically, he says that there is an emergency (not violating the laws of physics) where we work in a high level of the organization, in the program level. So we can think in the mind the same way: instead of thinking we are spirit inboded would be better think in the relation between the mind and the body in terms of functions. * Short digest of short interisting vídeo: https://youtu.be/m0YIm8p30aU .

Technology to study the brain[i]

The brain is a complex and sophisticated organ made by a lot of layers and billions of cells that is able to study itself. It is not simple, but today, scientists have three main ways to investigate a live brain safely, which is, not being harmful to someone and thus they try to relate our behavior with brain areas. The first method is electroencephalography (EGG), which was invented 100 years ago and it measures electrical waves that happen when the brain cells communicate with each other. It provides us information to identify precisely when electric signals occur during activities like learning or paying attention and registering them in just milliseconds and from that we can extract patterns to study diseases such as epilepsy. fMRI (functional magnetic resonant images), the second way to analyze how the brains work, is a technique to measure how quickly oxygen is consumed by brain cells showing which regions are involved during a cognitive or behavior activity.
