The Most Difficult Part of Investing

I’ve been investing some money for a few years now. One thing I noticed though is how it is a kind of character building if you follow Buffett’s strategy.

If you follow Value Investing, you basically estimate a company’s fair value and then decide whether you decide to buy or not based on that. After this point, the crowd may be ignoring you, going with you, or going against you. The stock will jump up and down each day. And somehow you just have to sit there and take the psychological beatings. If the price goes up, you have to remind yourself that that doesn’t guarantee you were right. If the price goes down you have to look through your reasoning again and hopefully you realize that your reasoning still holds. If not, you have to learn from it.

Sunlight is the Best Disinfectant

Quoting Alasdair S. Roberts:

Louis Brandeis is credited with writing that “Publicity is justly commended as a remedy for social and industrial diseases. Sunlight is said to be the best of disinfectants; electric light the most efficient policeman.” But why did Brandeis say that sunlight is said to be the best of disinfectants? Because he was referring to a statement by James Bryce in his 1888 book, The American Commonwealth.

Summary of On Settler Colonialism: Ideology, Violence, and Justice

This is my hand-written (zero AI) summary of the book On Settler Colonialism: Ideology, Violence, and Justice (2024) by Adam Kirsch. I've tried to extract the main ideas as well as possible, but would still encourage readers to buy the book for more details and a better written text.

On Settler Colonialism

After the October 7th attack, many people were first introduced to the concept of settler colonialism. However, it has been an well-known concept among academics for two decades. Settler colonialism argues that societies like the United States or Israel are illegitimate because they were created against the will of the native population. Since the concept is nowadays used for various political causes, it should be seen as an ideology instead of a historical concept.

How Is a Cult Defined and How Can People Get Out?

People often say that that members who vote party X or party Y are inside a cult. I think we can all agree that whatever political affiliation, cults are never a good idea. They might even play a role in the ever increasing polarization that we see happening. So out of curiosity, I opened the book Cults Inside Out (2014) by Rick Alan Ross to learn how a cult is defined and how people can get out.

What is a Cult?

According to Robert Jay Lifton in his paper Cult Formation (1981), destructive cults have three primary characteristics:

The Effect of Language in Propaganda

From Thought Reform and the Psychology of Totalism: A Study of 'brainwashing' in China by Robert Jay Lifton (1989):

For an individual person, the effect of the language of ideological totalism can be summed up in one word: constriction. He is, so to speak, linguistically deprived; and since language is so central to all human experience, his capacities for thinking and feeling are immensely narrowed. This is what Hu meant when he said, "using the same pattern of words for so long... you feel chained."

Summary of The Madness of Crowds: Gender, Race and Identity

This is my hand-written (not AI) summary of The madness of crows by Douglas Murray. Throughout the summary, I’ve tried to extract the core of the arguments as well as possible. For more information about the sources and for generally a better written text, I encourage readers to buy the book.

The Madness of Crowds

Every day we see the crowds behave irrational, this book goes into the underlying reasons.

From the nineteenth century onward, many people lost their meaning due to religions falling out of favor. Something new arose to fill the vacuum. This something came from academia into the mainstream since the 2008 financial crash. It isn’t hard to see why a generation that might never own a home is drawn to an ideology that promises to fix inequality.

Baudet on the Free Market

A strong argument in favor of capitalism is that “power corrupts” and a free market introduces competition to the market, so it distributes power. Based on this video.

Whether Settler Colonialism is Progressive

From On Settler Colonialism: Ideology, Violence, and Justice by Adam Kirsch:

If the definition of a progressive movement is that it believes the future can be better than the past, then the ideology of settler colonialism is not progressive, because it believes the past was better than the future.

Communism in a Nutshell

The idea of communism is that inequality is reduced by getting rid of rich people. Once communism gets under way, everybody is equal. Except the government. Or as Orwell wrote: “All animals are equal, but some animals are more equal than others”. In the DDR, you could recognize a party-member by the fact that they drove a Volvo. Normal people drove a Trabant.
