Infants understand that people pursue goals, but how do they learn which goals people prefer? We tested whether infants solve this problem by inverting a mental model of action planning, trading off the costs of acting against the rewards actions bring. After seeing an agent attain two goals equally often at varying costs, infants expected the agent to prefer the goal it attained through costlier actions. These expectations held across three experiments that conveyed cost through different physical path features (height, width, and incline angle), suggesting that an abstract variable—such as "force," "work," or "effort"—supported infants’ inferences. We modeled infants’ expectations as Bayesian inferences over utility-theoretic calculations, providing a bridge to recent quantitative accounts of action understanding in older children and adults.

A suspected MS-13 gang member has been arrested and charged with first-degree murder after a man was stabbed more than 100 times and buried in a Maryland park, authorities said.

Uber is truly a fascinating company. The 8-year-old firm is at once the source of strategy and business model admiration, as well as the source of a growing volley of corporate scandals and negative market reactions. The firm has wrestled with a barrage of setbacks culminating most recently with the ouster of its crestfallen co-founder and CEO, Travis Kalanick. There may yet be more trouble ahead. This time, however, for Uber’s drivers, who may face a decline in demand for their side hustling, as Uber recently announced the purchase of a fleet of 24,000 autonomous vehicles from Volvo.
This purchase marks a radical point of departure in Uber’s business model, which up until now has relied on an asset-light approach, which itself carried certain risks. By owning and operating a fleet, especially one where the driver is an optional accessory, Uber is signaling its bet on an autonomous future. Its drivers, who are generally considered fractional labor, have few rights if any in protecting their interests in this transition. Of course, Uber is not alone in making this very big bet on industrial-scale autonomy, as it joins the ranks of Tesla and many others that are successfully deploying autonomous vehicles. The difficulty for Uber in making this move, is that up until now its business model was relatively benign in pooling “stranded assets” and “stranded talent” into use. These stranded assets were a combination of peoples’ downtime and under employment, or their vehicles, which often idled on the side of the road or in their garages incurring carrying costs.
Trump traveled to Mar-a-Lago on Tuesday, hours after pardoning a turkey at the White House. Wednesday and Thursday were the president’s 27th and 28th days at his Palm Beach resort, according to a New York Times tracker. He also visited the Trump International Golf Club on Wednesday, where the White House said he handled “a full schedule of meetings and phone calls.” Reporters were not invited to join the president, but they were pretty sure Trump’s schedule also included some golf.
