many of you enjoyed "Bertrand Russell’s Chicken". This is the 𝙨𝙚𝙘𝙤𝙣𝙙 𝙥𝙖𝙧𝙩 𝙤𝙛 𝙩𝙝𝙚 𝙨𝙩𝙤𝙧𝙮. Russell’s parable of the chicken and Spencer Johnson’s Cheese story share a common lesson—life is unfair to those who don’t notice, deny and resist change. The cheese will move, and the farmer’s habits may change. The key to survival is not clinging to old realities but anticipating shifts and adapting quickly. Don’t take stability for granted—stay prepared, keep moving, and always look for new opportunities.

I keep going back to this question about #TemporalCreditAssignment and #HippocampalReplay:
As an "agent" you want to learn the value of places and which places are likely to lead to reward;

-1) if a place leads to higher than expected reward, you'll want to propagate back the reward info from the reward throughout the places that led to the reward. If replay does that you should see an increase of replay at a new reward site and the replay sequences should start at the reward and reflect what you just did to reach it. Right?

-2) if a place leads to lower than expected reward, you'll also want to propagate that lowered value, pretty much in the same way, so if replay does that you should see a similar replay rate and content for increased OR decreased reward sites. Right?

-3) if a place has had unchanged reward for a while and you're just in exploitation mode (just going there again and again because you know that's the best place to go to in the environment) then you shouldn't need to update anything and replay rate should be quite low at that unchanged reward side. Right?

That's not at all what replay is doing IRL, so does that mean replay is not used for temporal credit assignment? Or did I (very likely) miss something?

Male rats showed long-term impairment in learning, exploration, and rapid decision-making after heavy alcohol exposure for a month. Female rats did not show the same level of impairment.

Deep domain expertise for CPOs / Product leadership makes a lot of sense in early phase startups. In Scale-Ups the connection of domain expertise and leadership is unhealthy and, besides many other things, usually leads to bias-driven #decisionmaking.
Scaling and grown-up companies should seperate leadership and IC paths.

Adding to the conflicting evidence about the existence and strength of decision fatigue, a new study of over 203,000 medical decisions made by 200 Swedish nurses finds no evidence of decision fatigue.

So if you're having decision fatigue in the cereal aisle at the grocery store--no, you're not.

The Unintended Effects of Ethical Decision Aids in Organizations papers.ssrn.com/sol3/Delivery.
"Organizations frequently utilize Contemplation Questions in an attempt to foster ethical #decisionMaking and encourage employees to reflect on their actions. Presumably, they particularly target ’bad apples’—those (unknown) employees with a higher propensity for unethical behavior. However, our results indicate that CQs may inadvertently cause ’boomerang’ effects for this group. Individuals with lower #moral identities tend to use their interaction with CQs to justify their unethical preferences, increasing the likelihood of them acting unethically. While some CQs have positive effects on individuals with high moral identities, overall, the unintended consequences seem to be more significant. This aligns with the concept of motivated moral reasoning, where individuals rationalize their initial moral choices."

Emotion and #DecisionMaking annualreviews.org/content/jour

www.annualreviews.orgEmotion and Decision Making | Annual ReviewsA revolution in the science of emotion has emerged in recent decades, with the potential to create a paradigm shift in decision theories. The research reveals that emotions constitute potent, pervasive, predictable, sometimes harmful and sometimes beneficial drivers of decision making. Across different domains, important regularities appear in the mechanisms through which emotions influence judgments and choices. We organize and analyze what has been learned from the past 35 years of work on emotion and decision making. In so doing, we propose the emotion-imbued choice model, which accounts for inputs from traditional rational choice theory and from newer emotion research, synthesizing scientific models.

📰 "Genetic and Circuit Mechanisms Underlying Natural Variation in Value-Based Decision Making"

#Drosophila

bioRxiv · Genetic and Circuit Mechanisms Underlying Natural Variation in Value-Based Decision MakingGenetically encoded differences in value-related functions are believed to influence decision biases in animals, yet direct causal evidence remains scarce. Here, we demonstrate how naturally occurring genetic variation between two Drosophila strains leads to distinct choices in an egg-laying-based decision-making task, where both sucrose and plain substrates are viable options. We identify a pair of long-range GABAergic neurons, Earmuff, that lower an option's intrinsic value and are both necessary and sufficient for shaping the flies' preferences. Further analysis reveals that expression-modifying single nucleotide polymorphisms (SNPs) within introns of the gene encoding the RNA-binding molecule pumilio ( pum ) - a known negative regulator of the voltage-gated sodium channel NaV+ - exist between the two strains. These SNPs drive variation in pum expression within Earmuff, altering how each strain values the two substrates and biasing its decisions. Our findings establish a mechanistic link between genetic variation and the neural circuitry that governs value-based decision-making. ### Competing Interest Statement The authors have declared no competing interest.

📰 "An optimized appetitive visual short-term memory paradigm in Drosophila"

bioRxiv · An optimized appetitive visual short-term memory paradigm in DrosophilaThe ability to generate and recall memory is a behavior that is evolutionarily conserved across the animal kingdom from humans to jellyfish. Memory not only allows previous experiences to inform future decision making, but it also amasses information essential to life, such as memory of quality food sources, shelter, and predator-related associations. Associative memory forms a relationship between two or more distinct and initially unrelated stimuli and can be defined by its temporal characteristics, such as shortand long-term duration, as well as the memory being appetitive or aversive, generating approach or avoidance behavior, respectively. Since its introduction as a memory model in the 1970s, the fruit fly, Drosophila melanogaster, has emerged as a powerful tool for the investigation of memory-related processes. While a variety of memory paradigms have been used extensively in Drosophila, such as appetitive and aversive olfactory memory, the use of appetitive visual memory remains infrequent. A previous study introduced a visual shortterm memory (STM) paradigm that could be used for the study of both appetitive and aversive visual memory in Drosophila. However, this protocol required 50+ flies per condition, with three conditions per experiment, and 15 or more replications were frequently used to assess memory. As a result, this paradigm requires substantial numbers of flies, time, and is impractical for large genetic screens. Here, building upon this previous work, we describe an optimized appetite visual STM paradigm in freely moving Drosophila. Using recently published data on sexual dimorphism, innate color preferences, and borrowing practices from related appetitive assays, we have established an approach that minimizes confounding factors, such as sexually dimorphic starvation survival and sucrose preference, as well as pre-training color preference variation between groups. In doing so, we present an appetitive visual STM paradigm requiring substantially fewer replicates and numbers of flies to produce significant learning. ### Competing Interest Statement The authors have declared no competing interest.
