What to watch for

One of the worldās premier horse racing events begins this weekend under a cloud of suspicion and intrigue. Medina Spiritāthe controversial horse that won this yearās Kentucky Derby but flunked a test for performance enhancing drugsāwill be allowed to run at the Preakness Stakes under close supervision.
Bob Baffert, the horseās legendary trainer, is no stranger to drug scandals. In the past four decades, his horses have failed 30 drug tests. In some instances, those tests have been swept under the rug by racing officials with whom he has personal ties. Today, however, both Baffert-trained horses racing in the Preakness will be subjected to additional rounds of testing, and will be disqualified if labs find even trace amounts of the drug found in Medina Spiritās blood at the Kentucky Derby.
Charting whoās benefiting from privacy changes
Tech companies are starting to make it harder for advertisers to snoop on what consumers read, watch, and buy online. But thereās one notable laggard: Googleās Android operating system. While privacy changes are on their way to Apple devices and all major desktop browsers, there are no plans to bring similar protection to Android devices. That means the privacy benefits will go first to people who can afford iPhones and laptops, and last to people who rely on more affordable Android devices.

Ad industry observers expect that Google will eventually boost privacy on Androids by blocking advertisers from tracking what individual users do on their phones. But the company may be dragging its feet because it doesnāt want to disrupt the industry, which provides the lionās share of its revenue.
The C-suite to-do list
CEOs often use elaborate frameworks for setting corporate strategyāyet they still struggle to decide which projects to prioritize. Too many green lights, and everyone ends up feeling stretched.
But business strategy doesnāt have to be complicated, says Harvard Business School professor Felix Oberholzer-Gee. In fact, familiarity with some basic economics and employing one simple exercise are enough for most companies to decide what to move up the list. His approach has another important benefit: It helps clarify whether your company is actually good for customers, employees, and the world.

You asked about unmasking
If health officials are lifting mask mandates for the vaccinated, how do I know if the unmasked people around me have gotten their shots? How do I signal to them that I have?
In the US, the Centers for Disease Control and Prevention says fully vaccinated people can stop wearing face masks even indoors, with a few exceptions. The actual implementation of this advice will be up to state and local authorities, but this will likely be welcome news to many who are eager to get back to normalcy.
Yet just about a third of the countryās population is fully vaccinated, so the decision raises questions about unmasking. First among them: How can I be sure if someone I donāt know is fully vaccinated, and how do I let people know I am?
The answer isnāt quite clear yet. At the moment, the only proof of vaccination Americans have is the precious CDC vaccine card, but it doesnāt seem likely that people will be walking around cities wearing their vaccine card on their shirts. Not to mention, the card is just a piece of paper that is rather easy to falsify. The US still doesnāt have official vaccine passports, although some independent initiatives have emerged, including New York stateās Excelsior Pass, to digitally certify a personās status.
For now, it seems, much will come down to trust. After all, unvaccinated peopleāwho are at the highest riskāare supposed to wear masks anyway, which can protect them against the (hopefully occasional) unmasked non-vaccinated person.
