The Expertise Reversal Effect

I read an excellent overview paper that described the expertise reversal effect. It said (my summary):

Because experts have a deeper well of experience, it takes them longer to compare the redundant information with their past experience. That means the more expertise they have, the greater the drag on their cognitive resources the instruction will be.

Basically, over-explaining is bad. An intuitive notion, but I have upgraded the practice from β€˜annoying/boring’ to β€˜actively detrimental to development’. Perhaps the citation will help all of you as well.

Paper: Kalyuga, S. (2007). Expertise reversal effect and its implications for learner-tailored instruction. Educational Psychology Review, 19(4), 509-539.

[TOMT][TERM] What's the name of the effect where we easily spot published errors in our area of expertise, but then forget other areas could just as well have errors we don't realize?

Title. The classic example is like a doctor reading the newspaper who sees some medical info that he knows is wrong. Thus he won't really trust the medical stuff he reads in that newspaper, but he still trusts all the other stuff in there even though presumably experts in those other fields could spot similar falsehoods.

Google failed miserably at this question fwiw, even though I've seen it discussed a lot before across the web.

Here is my horror of horrors story. PVPS can be terrible. Had it vasectomy years ago and the pain was terrible. Tried reversals and injections on testicles. As a side effect my testosterone has dipped and I also have ED issues now. My life has been turned upside down. The vas is basically a bundle of nerves and blood vessels and can respond in unpredictable ways to vasectomy. 5-10% of men have long term pain. Dont get this vasectomy done, it can lead to chronic pain-inflict-to-me!

Zero Attack and Card Reversal Effects

Hello, So I was playing a game of Weiss with a friend and I have a couple questions about card mechanics/ruling. So he was playing adventure time and I was playing Bofuri, So Wildberry, princess base attack is 500, I played Flare Accel, Mii which has the effect of on play give an opponent -1000. My first question is does Wildberry princess die because its at -500 attack, and me second question is does it get its effect by dying this way.

[WildBerry, Princess] Level 0, 500 attack [AUTO] When this card becomes [REVERSE], if this card's battle opponent is level 0 or lower, you may [REVERSE] that character.
[AUTO] [(1) put 1 card from your hand into your waiting room & put this card into your memory.] When this card becomes [REVERSE] in battle, you may pay the cost. If you do, search your deck for up to 1 "Ooo" character, reveal it to your opponent, put it into your hand, and shuffle your deck.

[Flare Accel, Mii] Level 0, 1000 attack [AUTO] When this card is placed on the stage from your hand, choose 1 character in your opponent's center stage, and that character gets -1000 power until end of turn.
[AUTO] [(1) Put 1 card from your hand into your waiting room] When this card is placed on the stage from your hand, you may pay the cost. If you do, search your deck for up to 1 "Game" character, reveal it to your opponent, put it into your hand, and shuffle your deck.

In solid-state physics, how can a specific arrangement of atoms break time-reversal symmetry like in the crystal hall effect (CHE)?

To my understanding, time-reversal symmetry describes that some processes can be reversible in time (e.g. a car going at a velocity of v will travel with a velocity of -v when time is reversed) and some other processes are not symmetric to time, like a cup of coffee cooling down. I read about the crystal hall effect in antiferromagnets and am a little confused as to how this effect comes about.

e: Thanks for the awards and the many answers, I didn't think something this niche would get a lot of traction. the answers of u/Raikhyt, u/radioactivist, u/grolbol, and the link to the talk u/Deyvicous posted helped a lot.

Colleges Say Some Vaccinated Foreign Students Will Need American COVID Jabs Too, JHU's policy reversal leaves Chinese students worrying about mixed vaccine side effects, questioning if new rule is 'discriminatory'

Colleges Say Some Vaccinated Foreign Students Will Need American COVID Jabs Too

https://www.newsweek.com/colleges-say-some-vaccinated-foreign-students-will-need-american-covid-jabs-too-1622220

More than 500 colleges and universities in the United States will require students to be vaccinated against COVID-19 before beginning the fall semester, but a patchwork of rules about which vaccines satisfy the mandates has created uncertainty for international students.

For those who received vaccines in their home countries that are not approved by the U.S. Food and Drug Administration or the World Health Organization, most universities will require another jab. Among the vaccines in this category are those produced in China, Cuba, India, Kazakhstan and Russia.

Yamin said there is no clear framework in place to evaluate the efficacy of unfamiliar COVID-19 vaccines, and that leaving the decision up to individual institutions is producing "enormous inequities."

Some colleges, including Boston University, the University of Washington and the California State University system, will accept students who have received any vaccine.

Among the schools accepting only FDA- or WHO-approved vaccines β€” those produced by Pfizer-BioNTech, Moderna, Johnson & Johnson, AstraZeneca and Sinopharm β€” are Georgetown University, the University of Chicago and New York University.

"Requiring vaccinations is consistent with our intent to minimize the spread of COVID-19 within our own community, and more generally in New York City, and to enable more in-person on-campus activities," New York University Provost Katherine Fleming said in an April statement.

Under NYU's requirements, students who received other vaccines also must quarantine.

"All students who are not fully vaccinated and spend 24 hours or more in a country with a CDC Level 4 Travel notice in the 10 days immediately prior to arriving at NYU will be required to quarantine," the statement says.

"It makes sense politically," said Zoe Chen, a New York University student from Beijing, "but individually, I'll feel like, 'Why don't you just admit my vaccine? You are creating more trouble for me.'"

Chen said she has concerns about the safety of repeated COVID-19 inoculations.

"I will have some health concerns because I'm not sure if you can get re-vaccinated in a short period of time," she said.

Few studies have been done on the safety of mixing vaccine brands.

Can you build up a tolerance to 9-MBC's tolerance reversal effects?

9-MBC reverses my tolerance to supplements for me which is great! I'm having a great time enjoying all my favourite supplements like it's the very first time.

However, I'm wondering if this is a limited use to these reversal effects. Will I eventually build up a tolerance to the very substance that's reversing my tolerance? Is it theoretically possible?

Ideally I'd just be able to reset my tolerance once per month, or once per fortnight.
