Peeper Lessons

Do you hear them in the evening? Photo: David Huth. Source: Flikr. CC-BY-2.0 Nothing says spring in New England like peepers singing out in the dusk. When I drive home from work I can hear their chorus when I go by any wetland or even damp spots along the road. I don’t even have to roll down my windows. Peepers are small, usually less than an inch long, and they weigh just a fraction of an ounce. But when they get together, the sound [...]

Superhero Profits

“What’s your favorite superpower?” Source: Pxhere. CC0 That’s one of my favorite questions. It’s timely, and it gets to the other person to think about which of their own limitations they’d like to set aside – where they feel most constrained, and what they’d like to change. It also speaks to our current cultural moment, with superhero movies in the news. Last weekend, Marvel Studios released “Endgame,” one of the most highly anticipated films in recent memory. In fact, the build-up around “Endgame” reminded [...]

Shading our Perspective

How do you look at the world? Photo: Igor Ovsyannykov. Source: Fancycrave Everyone looks at the world through their own particular lenses: we’re limited by our own minds. We can never see anything truly objectively; we only know what we think we see. What we have are different shades of rose-colored glasses. This is a problem for investors. We tend to search for, interpret, favor, and recall information that confirms our preexisting beliefs. We call this “confirmation bias,” and it feeds our overconfidence. Suppose [...]

Rethinking Thinking

Why do new ideas come to us in the shower? Photo: Kevin Boyd. Source: Pixabay Creativity is a funny thing. New ideas are at the heart of the creative process, whether it’s science, writing, or finding the right music to energize our workout. Early cultures saw inspiration as a gift from the gods, a literal bolt out of the blue. That’s why so many ancient works of literature begin with a prayer to the Muse. But creativity is a disciplined process as well, where [...]

Devil Take the Front-most

Is this a winner-take-all world? Photo: Paul Bonhomme. Source: Flikr. CC-BY-SA 2.0 Increasingly, commerce is dominated by just a few big firms. We use iPhones to search for stuff on Google; we buy it on Amazon; and we tell our friends about it on Facebook. These tech titans provide everything we need, and they’re incredibly profitable. Normally, high profits attract competitors, forcing down margins. Consumers then benefit, as companies vie for their business, either through lower prices, better service, or some other innovation. But [...]

The Toothpaste Effect

You can’t put toothpaste back in a tube. Photo: M.M. Minderhoud. Source: Wikimedia That’s how l look at social media and the data giants. Assume, for the sake of argument, the worst is true: Facebook and Google and Amazon have been misusing “our” data. They’ve tracked us, profiled us, followed us, and manipulated us for their own nefarious ends. And assume, for the moment, that they lose control of the political agenda and the worst – for them – happens: they’re broken up, divested, [...]

Special Place, Sacred Space

Is there room for sacred space in our lives? 2019 Notre Dame fire. Photo: LeLaisserPasserA38. Source: Wikimedia There has been a massive outpouring of grief and concern since a massive fire swept through the Cathedral of Notre Dame last week. There has also been a massive outpouring of contributions to its ultimate rebuilding. French authorities have committed themselves to have the cathedral reconstructed in time for the 2024 Olympics in Paris. Apparently over €1 billion has been raised. Then, on Easter weekend, a local [...]

Is streaming the end of TV? Photo: Ki-keh. Source: Picography Streaming services have been multiplying, with Netflix, Hulu, and the recently announced Disney Plus service. Now, you can take your PC anywhere and watch whatever content you want any time you like. Is sitting in the living room and arguing over who gets to control the remote just over? TV used to be mass entertainment. People had a set in their living room, and programmers created content that could appeal to almost everyone. This [...]

Droning On

Are drones taking over our lives? Photo: Ki-keh. Source: Pixabay It may seem like it. Drones are everywhere. Some stories about the fire at Notre Dame Cathedral featured accounts of drones showing firefighters where to point their water hoses to maximum effect and giving other critical information. They’ve also been essential in assessing the damage after the blaze was put out. In fact, drones equipped with thermal imaging systems can provide real-time evaluations in all kinds of emergencies, from forest fires to search-and-rescue to [...]

Getting a Good Start

How do you start your day? Photo: Viktor Hanacek. Source: Picjumbo I like to cook up a batch of oatmeal, when I have the time. Some fruit, milk, and a little sweetener make it very filling and nutritious. Doctors tell us that it’s important to have breakfast, to replenish our body’s store of energy and nutrients, to keep from getting hungry later and overeating. The important thing is to get started, to begin your day well. It’s the same thing with investing. It’s critical [...]
