For the past month, I have been reading "The Wisdom of Psychopaths" by Kevin Dutton which delves into traits, behaviors, and motivations behind psychopaths. This book isn't just about serial killers but rather also the "successful" functional psychopaths such as stockbrokers, politicians, and business executives. You can read an excerpt from the book here if interested. A few interesting takeaways that I have had from the book so far are the innate cues that some people have on picking up on psychopathic cues. This is like speaking to someone and getting the heebie-jeebies from them for some reason. Apparently, women are more perceptive to this than men.

So, I'm curious if you have ever met a person that gave off that vibe, and what in particular gave you that vibe?

Intermittently, for the past 15 years or so, logic has been an interest of mine. Back then I had trouble understanding exactly why certain things people said sounded so right/wrong, and how could I come up with proper responses.

Among others, in this time I've read one great book on informal logic (which I lost, unfortunately), quite a few articles, and studied the first chapters of the stupendous Gary Hardegree's symbolic logic.

Even though I love the subject, it is hard to sustain motivation alone. I wish to acquire a firmer grasp of logic and its applications to philosophy. Hence the suggestion of forming a study group.

It is my understanding that most Tilderinos are in STEM, especially areas surrounding computer science. So I anticipate that many users have an understanding of logic that greatly surpasses my own. Because of that, for some, a philosophical logic study group may seem too elementary to be of any value. Others may find it interesting to approach logic from a philosophical point of view.

In any case, the idea is to start from scratch. Besides the ability to read and write in the English language, no previous knowledge is required. No mathematics either.

I have two initial proposals.

1. An Illustrated Book of Bad Arguments

This one is ideal for a light, relaxed approach.

This awesome book describes 19 common logical fallacies using accessible language, with clear examples and suggestive illustrations. Not very technical, and a lot of it is well-known territory if you have an interest in logic. One chapter for each fallacy, each chapter is one page long. A great conversation starter.

2. Symbolic Logic: A First Course, by Gary Hardegree

I would choose this one myself. Hardegree is a wonderful teacher.

This book is one of the best teaching materials I have ever known, and surprisingly superior even to paid alternatives. A more proper introduction to logic. Hardegree is an excellent teacher, introducing concepts with precision in accessible language. The progression is smooth, you never feel that the exercises are either too easy or too hard. And there are plenty of exercises (with answers!) which are great for self-study.

We could start with either one of these books and follow from there. Just meeting once a week (or maybe biweekly) to discuss the chapter or chapter section we studied in that period.

I understand a lot of people like to do that kind of stuff on Discord, so that's a possibility.

From Wikipedia:

A cognitive bias is a systematic pattern of deviation from norm or rationality in judgment. Individuals create their own "subjective reality" from their perception of the input. An individual's construction of reality, not the objective input, may dictate their behavior in the world. Thus, cognitive biases may sometimes lead to perceptual distortion, inaccurate judgment, illogical interpretation, or what is broadly called irrationality.

For obvious reasons, it is much easier to identify biases in others than ourselves. Nevertheless, some of us went through practices (such as psychotherapy), experiences, and introspection that allowed us to put our biases in check. So, instead of scrutinizing the behavior of others (something that comes naturally to us, especially on the internet), here I ask you to exercise some self-criticism. What intellectual tendencies you have that obsessively repeat themselves in different contexts?

I should note that cognitive biases do not always lead to bad outcomes or falsehoods, as stated in Wikipedia:

Although it may seem like such misperceptions would be aberrations, biases can help humans find commonalities and shortcuts to assist in the navigation of common situations in life.[5]

On this thread, I am deliberately not asking about political bias or anything of the sort, including all the juicy controversial subjects surrounding it. Anything that often leads to uncivil discussion should be considered out of bounds.

For inspiration, look at this list (you don't need to identify a named bias, though... a subjective description of something you believe to be a form of bias is enough).

You're guaranteed to have at least the same level of comfort and subsistence you currently have. Anyone in the present that depends on you financially will be taken care of. Other than that there are no guarantees whatsoever. You cannot go back. It's definitely a gamble. Can you resist the curiosity?

There were a ton of interesting ideas proposed on the previous thread

We could all just watch whatever we want, whenever we want and have periodic posts.

Someone smarter than me could schedule a Discord (whatever that is).

What are some of the best, most influential, memorable, or otherwise impactful short stories that you've read throughout your life? If possible, please link to a PDF or other text so that we can enjoy it too.

"Youth" by Glass Animals and "Yulia" by Wolf Parade simply gut me. They're not associated with anyone in my life; I'm just extremely susceptible to their emotional content. Got any music like that? Do you seek out the listening experiences for the catharsis?

Do you like them? Hate them? Don’t care about them? Take pride in them?

What do you consider good/bad achievements?

Do they affect how you play games?

Do you feel you have to get most/all of them?

What games have used them to novel effect?

Anything else you want to say about the topic is fair game as well. This is an open door for any discussion related to achievements.

I've been doing a lot of thinking about my own attention lately, and I'm curious to hear others' thoughts. I don't want to prime the thread, but I'll probably type up some of my own considerations in a comment later.

Any and all comments/experiences are welcome, especially those from people with ADHD or other similar conditions that impact executive functioning.

• Are you happy with your ability to manage your attention and focus?
• Do you feel like you're in control of your attention? Is it something you have to manage?
• Do you feel as if anything has changed over time?
• How would you describe your attention/focus to someone who experiences theirs in a different way from you?

Those are simply guiding questions to get the ball rolling, but I don't want to limit the conversation to just them. Really I'm interested in hearing anything anyone is wanting to share about their relationship with attention and focus.

(Also, how open are you to being dissuaded from it? I'm always open to new information, so if you're concerned about me embarrassing myself in public with these ideas, enlighten me, by all means.)

Two examples come to mind for me.

• Astrology. I don't think the positions of the stars have any actual bearing on people's destinies, but there are definite traits that seem common to the individual signs, across cultures and eras. Perhaps there's a natural cycle of some sort that affects our collective psychology or even biochemistry and we misattribute zodiac stereotypes because it happens to align with the celestial "movements"?

• Graphology. The notion that particular characteristics or tendencies could be expressed in something like handwriting doesn't sound unreasonable to me. Our minds physically express many things in our body language, and I could see how handwriting might essentially be an extension of that, or another translation.

Of course, this could just be self-selection and delusion, but these are likely complex issues and there's still quite a lot we do not understand.

How would you all feel about a virtual film festival?

We nominate candidate films, documentaries or shorts, focusing on things ​rarely watched, but that might provoke an interesting discussion.

We watch candidate films over maybe a three week period, watching maybe 3 times as many films as we nominate.

Then discussion ensues.
