@alex_nafnlaus I don't mean that purpose is ignored, but that purpose is not the origin of any given behavior.

Just like when learning to walk you perform all possible leg movements. As an adult, you keep reproducing those who make you walk.
@alex_nafnlaus As a complementary example to examine the difference from a different angle,

do we decide to walk towards the fridge because we're hungry, or to satiate hunger?
@alex_nafnlaus As a third example, if our behavior happened because of its purpose, shouldn't non-sentient entities be inanimate?

When people tell you their problems, they often tell you bandaid problems: problems which can be solved using bandaid solutions.

When one of their mental patterns is part of the root cause, they will not mention their real problem.

This is a rational behavior.

(thread)

[1/4]
If the problematic mental pattern of theirs was perceived as net negative, they would already have abandoned it.

If they keep holding onto it, it must be because it is subjectively considered as net positive, on the basis of past personal emotional experiences.

[2/4]
It makes then sense for the brain to hide the real problem, for solving it would mean abandoning a behavior which is considered net positive.

Why would the brain do something this irrational?

CHOOSE LINDY OBJECTIVES (thread)

1/ The Lindy principle: for something non perishable, age is an estimate for life expectancy

Example: a book which has been popular for 100 years is likely to be still popular in 100 years
Last year’s bestseller is unlikely to be popular in 100y
2/ Lindiness is an inverse measure of number and specificity of assumptions needed for survival.

The environment constantly changes; something which survived for long lived through many different environmental conditions and demonstrated survival to change.
3/ Lindiness is not only related to age.

A book which is popular across many counties is less likely to require assumptions which are true for a single country, and is therefore Lindier than a book which is only popular in one country.

ERGODICITY AND ANTIFRAGILITY
(thread)

1/ What is the link between ergodicity and antifragility?

Why do people participate to non-ergodic activities?

Why do they take so much risks in ergodic activities that they make them non-ergodic?
2/ First, a definition. Something is ergodic if its expected outcome coincides with the time average.

For a better definition, please check the picture below.

(Or read this excellent paper: …godicityeconomics.files.wordpress.com/2018/06/ergodi…)
3/ Ergodicity is not only the property of an activity, but of an activity performed by an actor with a given exposure.

For example, Russian Roulette is non-ergodic for the Russian Roulette player but is almost ergodic for a company hiring Russian Roulette players.

#Learning ‘Any thing can happen’ culminates from the concept that market movement is a factor of numerous known and unknown random variables; today’s gap down which is on account of a random variable called Trump/Iran variable shifted the entire market direction upside down...
.... in an otherwise up trending scenario; charts don’t reflect all random variables; it reflects only known random variable and markets expectation on them. For eg, coming budget is a known random variable, economic events like data announcement, monetary policy etc ....
.... are known random variables. Known random variables are already known by market but for its outcome. This will adjust the chart structure if the outcome of the known random variables is not what market expected / not what was priced in; Unknown random variables on the other..

I need to motivate and write sumthin for my blog but everything is either too "big and messy" or "feels not worth the effort now"

Until I got this idea to play with FANDOM TERMINOLOGY SHITFIGHTS

(Oh snap! Muddy-kun is gonna frick this one up in classic gettit-wrong fashion)

No..wait... Have been watching it on a certain "grey" aggregator site, fun to read comments too.

Of course commenters are all sloppy with terms: "GAY" "Yaoi" "shonen-ai".

By ep5 all I can guess is that one chara has a man-crush and another, a roomie. Read in what you will -- or am I erasing? Or am I reluctant to be trolled by the writers?

Besides the point. What we got here is an almost genre-perfect take on a "guys friendships" story.

Learning about surface vs deep learners. @lsu Teaching Colloquium. Thinking about implications and applications of learned information.
Learner needs to regard info as important, intriguing, or beautiful. Then deep learning occurs. Learner needs to be in charge of the question. But, few students will not take a deep approach to learning.
Students are conditioned to take a surface approach to learning. School is the biggest place that conditions surface learning. #KenBains #learning #whatTheBestCollegeTeachersDo

Given that Supreme Court justices are appointed for life, is it possible for them to be forced off the bench if they don’t want to go?

Yes — but it’s a most highly unlikely prospect. washingtonpost.com/news/answer-sh…
In U.S. history, one justice was impeached, but not convicted, and one justice resigned under the threat of impeachment.
The single justice impeached but subsequently not forced out was Samuel Chase, a longtime Maryland legislator who was appointed to the court as an associate justice by President George Washington on Jan. 26, 1796, and who served there until his death on June 19, 1811.

My experience with learning modes - Text vs Video content

- Due to concentration lapse, it's easier to drop off for a few minutes from a video content (> 5 mins)

- Concentration lapses happen in text too, but its easier to re-read the para vs rewinding the video

#learning
- For consuming the same amount of content, text form is less time consuming than videos.

- To explain complex topics/situations, texts usually take more time building up the context than videos.
- We try to understand things by building mental imagery, that way videos are more efficient than text because it takes a bit of time to build the mental imagery from interpreting the text and yet you might not be building the right imagery.
