Too fast, too furious? Ocelot and sloth caught in highish-speed chase

After a team of biologists capture on camera a "considerably high speed (for a sloth)" escape, Feedback ponders if the Fast & Furious action movies need to move aside

Too fast, too furious

The Fast & Furious action movies now have a companion in the world of animal study. A team of biologists videoed a furious and fast – well, relatively fast – incident, which they describe in a paper called ā€œā€œ.

The , they explain, ā€œshows the sloth trying to escape at a considerably high speed (for a sloth) by inverted quadrupedal locomotion along a horizontal fallen tree lying across the mineral lick at a height of ~30 cm above the ground. The ocelot tries to bite the sloth’s hands and slowly follows it on top of the branch.ā€

Spam-filtered lives

An advisory memo for lawyers has made Feedback muse on an unanswerable question: how much have spam filters altered the course(s) of history?

How many meetings didn’t happen because email spam filters swallowed the invitations? How many agreements went unconsummated? How many other kinds of consummation were banjaxed into spam-filtered-interruptus?

The legal advisory, by attorney Barron Henley, explains that ā€œA high percentage of malpractice practice claims and practice management problems are caused by communication breakdowns.ā€ He warns especially that, ā€œThanks to spam filters, email address auto-complete and various other issues, sending an email is no guarantee that the intended recipient actually received it.ā€

The University of Notre Dame, Indiana, published Henley’s paper, giving it the title ā€œCommunication breakdown – It’s always the same (but it’s avoidable)ā€. As an unusual introduction to that concept of always-the-same-ness, the top of the paper’s very first page says: ā€œDISCLAIMER – The information and procedures set forth in this practice manual are subject to constant change.ā€

One of the many unsolvable questions of recent history is: how many lawyers never saw Henley’s warning about communication breakdowns – because their spam filters swallowed it?

In God (and AI) we trust

ā€œ.ā€ That is the title of a new study in the Proceedings of the National Academy of Sciences. By Mustafa Karataş at Nazarbayev University, Kazakhstan, and Keisha Cutright at Duke University, North Carolina, it reads like a thrill ride, with surprises around every corner.

The study was a series of experiments involving different people, some online from the US or Turkey, others in Turkey in ā€œa mid-sized mosqueā€ or on a ā€œnearby street without a view of the mosqueā€ or in a dental clinic. At the beginning of each experiment, some people were asked to write about God, others to write about some other topic (mostly, how they had spent the earlier part of their day).

One experiment asked 405 people if they would prefer getting recommendations – about movies, romantic partners and 22 other things – from a human or from an algorithm. Other experiments involved choices between ā€œhit Turkish songsā€, ā€œmutual fundsā€, ā€œomega-3/fish oil supplementsā€, hypothetical ā€œhealthy protein barsā€, dental (implant and root canal) treatments or cryptocurrency prizes.

Each choice was between something supposedly recommended by a human or a similar something supposedly recommended by an algorithm. At the end of each experiment, people were asked to indicate ā€œthe extent to which they thought about God while participating in the studyā€.

All these (and a few other) things having been considered, Karataş and Cutright leave us, their readers, to ponder the lesson they say they have learned. Specifically this: ā€œThoughts of God lead individuals to feel smaller, rendering them more likely to recognize the fallibility of humans. They therefore find it less essential to rely on humans when making decisions and are more accepting of AI-based recommendations.ā€

Weary of ambiguity

Are you Weary of research-titles-that-are-ambiguous fame? If you are Daniel Weary, co-author of the study ā€œā€œ, the answer is yes.

If you are not Weary, or anyway not that Weary, Feedback poses you this riddle: is Weary’s calves study about the muscular back part of the lower leg or is it about young cows? Feedback urges you to read the study and decide for yourself, but here is a not very helpful hint. The first two sentences of the paper say: ā€œNegative emotional states are known to interact, potentially aggravating one another. In this study, we used a well validated paradigm (successive negative contrast, SNC) to determine if pain from a common procedure (disbudding) influences responses to a reward downshift.ā€

, who is at the University of British Columbia, Canada, co-wrote another study with a challengingly ambiguous title – ambiguous, that is, if you know or suspect that thick, soft cloth made from a pressed mass of fibres is able to feel emotions. That study, published as a chapter in the book Advances in the Study of Behavior, is called ā€œBehavioral evidence of felt emotions: Approaches, inferences, and refinementsā€.
