A while ago I posted a question on Kavua and Kahnemann Tversky. Here is part of a response I wrote to a ben Torah who was kind enough to forward me some sources including this analysis from Prof Aumann
You really should consider reading thinking fast thinking slow or a summary as I think it gives extremely important insights into the human thought process which a Poseik,Ben Torah needs to understand. (nb-I received 2 or 3 responses saying I don’t know Kahnemann Tversky but…) …..
the Chida in the Dropbox Aumann piece. It seems to me that this is easily translatable into an the behavioral economics framework along the lines that I was thinking. In the middle of the marketplace situation we have absolutely no information and so all of the things being equal (which of course is really never the case) we used pure statistical probabilities. In the case of going in the store in theory the individual in many respects is trying to remember which store it was in or why he picked it and maybe anchoring this in a poor heuristic , That’s we say 50-50
I’m not sold on it but I do think at least it’s a possible explanation

Is it your experience that pick up mincha minyanim (i.e., outside a formal synagogue setting) often skip tachunun (I’m not talking about at a simcha)? If so, why?
- Rabbi Aryeh Lebowitz -From The Rabbi’s Desk – Some Common (and Uncommon) Purim Questions
Issues regarding 1) birchat hamazon bein hashmashot on Shabbat (which day is it really?) 2) washing before touching the megilla, 3) touching a human skull, 4) balancing simchat purim with physical and psychological damage you may cause.
It seems to me one can often find sefarim in a synagogue with individuals’ names in them, especially children’s. The names may or may not be those of members or even recognizable to members. It is possible that people forgot them or left them as “donations!” What is the shul’s responsibility in the context of returning lost objects? What about an individual in the synagogue? May such sefarim be used?
- Rabbi Nosson Rich -Mishna Berura Yomi: Hilchos Purim 694-2
Review of some rules for machzit hashekel and matanot l’evyonim or Purim. Purim halacha does raise the question of how much one must check tzedaka collectors during the rest of the year.
- Rabbi Michael Bleicher -Tevilah on Shabbos: When the Neshama Yeseira Encounters Kedusha Yeseira
What is the mitzvah status of going to the mikveh bzmana (at the proper time)? Especially since we add days to the definition anyway? What about going to mikveh on Shabbat—there are issues, but we overcome them to get an oxycontin rush!
- Rabbi Dr. Jeffrey Woolf-What is Mesorah? What isn’t Mesorah?
Defining Mesorah is important given current halachic debates. It may mean identifying [realia] but in much of today’s discussions it is about the process halacha follows. The Bavli was accepted and change can come about through the halachic mesorah process, but only through chachmei hamesorah. We reject academic approaches because they do not put the emphasis on the halachic process and how it views influences to be accepted or rejected. We take the long view. (Amen!)
- Rabbi Zvi Sobolofsky-Hilchos Aveilus Marathon Shiur Part 4

- Rabbi Moshe Taragin -Mussar Shmooze Parshat Teruma 2017: The Centrality of Talmud Torah
Don’t just be a consumer/listener, but be an active reader/learner. Be able to answer the question, “What do you live for?” You need to expand your time (i.e., early a.m./late p.m.) to provide time to learn in a normal life (Amen!) Serve others materially and spiritually and daven as if you are standing before HKB”H!

- Rabbi Yehoshua Grunstein-Shul Protcol on a Fast Day without…Fasters
Various opinions on how many fasters one needs in a minyan in order to add aneinu to amidah or read Vayichal. It may well be a function of other community priorities (e.g., chinuch/kiruv).
- Rabbi Shay Schachter -The Conflict of Mesorah for the Contemporary Jew – Part 2
More on R’YBS and the importance of the mesorah. Here his famous father (intellectual) vs. mother (experiential) mesorah dialectic is discussed. Some interesting thoughts on the history and short falls within the chassidic and mitnagdic communities as well as examples of current problematic rabbinic statements. The universalism/ particularism balance is a delicate one.
- Rabbi Chaim Brovender-Purim Clothing and Costumes and Kavod and Tifferet
The Kohain Gadol and Yosef both show the importance of the message of clothes. There is a tie between tshuva (repentance) and geula (redemption). The tshuva in the megilla was incomplete and thus so was the redemption

- Rabbi Zvi Sobolofsky-Overview of the 4 Mitzvos of Purim
