Different Parts of the Brain

The degree of reward-sensitivity is caused by a difference in brains🧠: decisions are based on whichever part of the brain that sends stronger signals

“old brain” = limbic system; focuses on emotions/instinct😭🤪🙄💅😂
“new brain” = neocortex, focuses on rationality/language/planning/thinking 💭📝🗣️📈

Extroverts = more responsive to old brain, more ambitious, more responsive to dopamine (proven by Cornell professor Richard Depue)

Alan🧓: spends💰💰💰on buying technological stocks and loses nearly all.

Context: 2008 financial crisis

Help introduce the concept of reward sensitivity, showing the harm of a “buzz”, that causes people to ignore the risk that were suppose to take care

-Known for thinking carefully while those around him loses heads

At the height of technological boom:

-didn’t make a soon invest

-having a careful think to take his decision

-having 💬💬💬 analyzing why the tech-fueled bull market wouldn’t last

His key🔑 to success was maintaining calm, which enabled him to detect the risks and the find strength to insist on his idea when everyone chooses to invest the tech market.

Old & New brain

haochengzhang15208bisz — 2024-10-24 00:16:55 UTC

People do what they do due to the intervene of old and new brain

-🧓👵👴old brain: pleasure center, greediness of people

-new brain (neocortex): responsible to make decisions, such as planning, language, more rational in a nutshell

Buzz🐝🍯

A rush of energized, enthusiathic feelings (extrovert easier to get an extra buzz) that will motivate people to be highly reward-seeking

Conclusion

Alan’s and Buffett’s example contrast in how people respond to a sudden “buzz” 🐝🍯

Alan, before the finance crisis of 2008, got empowered by the “buzz” and spend all money buying the stock shares📈in tech company which he is confident about, and this confidence eventually makes him loses nearly all its investments💰😢

Buffett, as another example, has the ability to think🤔against the “buzz” even though the chance of earning profit 💵💵💵 is right in front of him. He then finally comes out with a different view comparing to the majority of people that this prosperity will not last long. And his decisions in insisting his own ideas make him succeed😎🙀👍

The author is inferring her audience that it is true that the reward sensitivity can be beneficial that it gives the motivation for people to change, but it is also essential to evaluate the risks and the benefits hinders behind the “buzz”
