Week in Review: April 27th to May 2nd

It's Sunday, May third, and welcome to HigherIQ. We covered a lot this week. Six episodes, six different topics, and a lot of information to hold onto. Today we're doing something different: a recap of the week, one key insight per episode, so you walk into Monday remembering what you learned and ready to talk about it. On Monday, we talked about how mergers and acquisitions actually work, and why the government can kill a deal between two willing companies. The key insight: the government isn't just blocking mergers between existing competitors anymore. It's blocking deals where a dominant company is trying to buy a smaller company specifically to prevent it from becoming a competitor in the future. Visa tried to buy Plaid not because Plaid was competing with Visa but because Plaid might eventually threaten Visa's business. The DOJ killed the deal. Adobe tried to buy Figma for the same reason. That deal died too. The same law that broke up Standard Oil in 1911, the Sherman Antitrust Act, is the law being used today to evaluate whether SpaceX should be allowed to acquire Cursor. The companies change. The question doesn't: does this deal make the market more competitive or less? On Tuesday, we talked about pain. The key insight: pain is not a direct readout of how much damage your body has sustained. It's a judgment your brain makes about how much danger you're in. Seventy five percent of badly wounded soldiers at the Anzio beachhead in World War II refused morphine because their brains, processing the context of survival and evacuation, had turned their pain down. A neuroscientist named Ramachandran used a simple mirror to eliminate phantom limb pain that no surgery or medication could touch, because the pain was being generated by an error in the brain's model of the body, not by any injury. The brain doesn't just receive pain. It creates it, amplifies it, and in the case of chronic pain, learns to produce it long after the original injury has healed. On Wednesday, we talked about why emotions have a body. The key insight: your body doesn't just express emotions. It helps generate them. William James argued in 1884 that you don't cry because you're sad, you're sad because you cry, and modern research has partially confirmed it. People who receive Botox that prevents frowning report feeling less negative emotion. Emotional tears contain different chemicals than reflex tears, including stress hormones and natural painkillers, and crying is essentially a chemical reset that flushes those hormones out of your body. And broken heart syndrome is a real cardiac condition where intense emotional stress causes the heart to physically change shape, sometimes fatally. When someone says heartbreak hurts, they're describing a neurological and cardiac fact, not a metaphor. On Thursday, we talked about the Federal Reserve. The key insight: the Fed controls interest rates, which affect the cost of everything you borrow and the return on everything you save, and it was designed to be independent from the president so that no politician could juice the economy before an election at the cost of inflation afterward. That independence has been tested by every president, but the historical lesson is clear. In the 1970s, Fed Chair Arthur Burns caved to Nixon's pressure and kept rates low. The result was the worst inflation in modern American history. It took Paul Volcker raising rates to nearly twenty percent and triggering a recession to fix it. Jerome Powell announced he would stay on the board as a governor after his chairmanship ends, the first former chair to do so since 1948, to prevent the current administration from assembling a majority of its own appointees on the board. On Friday, we talked about the presidential pardon. The key insight: it's one of the most absolute powers in the Constitution. No judge can reverse it. No court can review it. No Congress can override it. Hamilton argued it was necessary so that justice wouldn't be too harsh and so presidents could heal the country in times of crisis, and Washington, Lincoln, and Carter all used it that way. But the same power has been used by Ford to pardon Nixon before he was charged, by Clinton to pardon a fugitive donor and his own brother, by Trump to issue fifteen hundred January 6 pardons and preemptive pardons for political allies, and by Biden to pardon his own son. No president has attempted a self-pardon. No court has ruled on whether one would be valid. The most powerful pardon may be the one that hasn't been used yet. On Saturday, we talked about dreams. The key insight: you spend roughly six years of your life dreaming, and science still can't fully explain why. But the recent research is remarkable. In 2021, four independent labs communicated with people who were actively dreaming, asking them math questions that the sleeping subjects answered correctly using eye movements. Harvard researchers showed that amnesiacs who couldn't remember playing Tetris still dreamed about it, meaning the dreaming brain processes experiences the conscious mind can't access. And threat simulation theory argues that dreams may have evolved as survival rehearsals, which would explain why seventy percent of dream emotions are negative and threatening scenarios are overrepresented in dream content. Your sleeping brain isn't offline. It's computing, sorting, rehearsing, and processing, in a state you'll barely remember by breakfast. That was the week. Six episodes, six insights. If you only remember one thing from each, remember this: mergers can be killed to protect competitors that don't exist yet. Pain is a brain judgment, not a body measurement. Your body builds your emotions, not just the other way around. The Fed's independence is the reason you're not living through 1970s inflation right now. The presidential pardon has almost no guardrails and never has. And your dreaming brain is doing work you'll never consciously remember. We'll be back tomorrow with something new. Stay informed, stay curious, and we'll see you tomorrow.
