NLG (natural language generation) may be too powerful for its own good. This technology can generate huge varieties of natural-language textual content in vast quantities at top speed.

Today’s most sophisticated NLG algorithms learn the intricacies of human speech by training complex statistical models on huge corpora of human-written texts

The algorithm can generate samples of news articles which human evaluators have difficulty distinguishing from articles written by humans. It can also generate a complete essay purely on the basis of a single starting sentence, a few words, or even a prompt

This is the fog of late pandemic, and it is brutal. In the spring, we joked about the Before Times, but they were still within reach, easily accessible in our shorter-term memories. In the summer and fall, with restrictions loosening and temperatures rising, we were able to replicate some of what life used to be like, at least in an adulterated form: outdoor drinks, a day at the beach. But now, in the cold, dark, featureless middle of our pandemic winter, we can neither remember what life was like before nor imagine what it’ll be like after.

The sunniest optimist would point out that all this forgetting is evidence of the resilience of our species. Humans forget a great deal of what happens to us, and we tend to do it pretty quickly—after the first 24 hours or so. “Our brains are very good at learning different things and forgetting the things that are not a priority,” Tina Franklin, a neuroscientist at Georgia Tech, told me. As the pandemic has taught us new habits and made old ones obsolete, our brains have essentially put actions like taking the bus and going to restaurants in deep storage, and placed social distancing and coughing into our elbows near the front of the closet. When our habits change back, presumably so will our recall.

The share of Americans reporting symptoms of anxiety disorder, depressive disorder, or both roughly quadrupled from June 2019 to December 2020, according to a Census Bureau study released late last year. What’s more, we simply don’t know the long-term effects of collective, sustained grief. Longitudinal studies of survivors of Chernobyl, 9/11, and Hurricane Katrina show elevated rates of mental-health problems, in some cases lasting for more than a decade

Ad-driven search engines, like social media platforms, are designed to reward clicking on enticing links because it helps the search companies boost their business metrics. As researchers who study the search and recommendation systems, my colleagues and I show that this dangerous combination of corporate profit motive and individual susceptibility makes the problem difficult to fix.

It is in the search engine companies’ best interest to give you things that you want to read, watch or simply click. Therefore, as a search engine or any recommendation system creates a list of items to present, it calculates the likelihood that you’ll click on the items.

Similar to problematic social media algorithms, search engines learn to serve you what you and others have clicked on before. Because people are drawn to the sensational, this dance between algorithms and human nature can foster the spread of misinformatio

The S&P 500 climbed 1.3% to reach an all-time high, its first record since Feb. 16. The Dow Jones Industrial Average added 350 points to hit another intraday record. The Nasdaq Composite jumped 2.5% amid a rotation back into tech shares. Tesla was up 4%. Apple, Facebook and Netflix all jumped at least 2%, while Amazon, Alphabet and Microsoft shares were also higher.

Tech and growth stocks are rebounding from a swift correction triggered by rising interest rates. Higher rates make profits in far-off years seem less attractive to investors and can knock down stocks with relatively high valuations.

“The stimulus is beating the virus at least as far as the market is concerned,”

Social platforms let us stay in touch with friends and forge new relationships like never before, but those increases in communication and social connection may come at a cost. In a new paper published in the Journal of Experimental Social Psychology, researchers showed that those who documented and shared their experiences on social media formed less precise memories of those events.

n a series of three studies led by Diana Tamir of Princeton University, researchers explored how taking photos and videos for social media affects people’s enjoyment, engagement and memory of those experiences.

Tamir and her team found that sharing experiences on social media did not seem to affect how much people felt that they had enjoyed the experience or were engaged. However, those who wrote down, recorded or shared their experiences performed about 10% worse on memory tests across all experiments.

Our five senses–sight, hearing, touch, taste and smell–seem to operate independently, as five distinct modes of perceiving the world. In reality, however, they collaborate closely to enable the mind to better understand its surroundings. We can become aware of this collaboration under special circumstances.

In some cases, a sense may covertly influence the one we think is dominant. When visual information clashes with that from sound, sensory crosstalk can cause what we see to alter what we hear. When one sense drops out, another can pick up the slack.

People with synesthesia have a particularly curious cross wiring of the senses, in which activating one sense spontaneously triggers another.
