Human Limitations

by Olga Werby • August 6, 2025

We live in a vast universe that spans enormous scapes of time and space. But humans evolved to understand information in relatable quantities at a human scale. We conceive landscapes mostly in chunks we can easily walk, connected loosely by strands of distances we can comfortably drive. We live in the now, but relate to the future in terms of a past that we dimly remember. We can make plans just within a very narrow scope of time — days, perhaps weeks. The future is always elusive and vague. We don’t comprehend spans of time outside of our experience. The span of a million years, ten million, a hundred million, or even just a thousand are concepts which we can intellectualize about but can’t really feel. Even in our interactions as members of a species, we can each just maintain a web of a few dozen relationships. Space, time, and human interactions are limited for us. We don’t process and, thus, don’t truly comprehend, information of large or very small scales that are beyond our direct experience. It’s not who we are as humans. This has all sorts of ramifications beyond the obvious. It’s why it’s easy for us to…

The Fragility of Normal

by Olga Werby • February 12, 2023

Fortune: May you live in interesting times

We all want to go back to normal. We cry about it and complain: “Enough is enough. We want our lives back.” This need to “go back to normal” is always with us, although maybe on a different scale post-pandemic. But even before Covid, there were always things that disturbed our perception of normal: new teachers, new housing, new jobs, new routines, stores and restaurants closing, cars that break down, challenging illnesses, new bus routes. Towards the end of our vacations, we come to realize that, although adventures are fun, it is good to be home where things are as we expect them to be. This want of predictability, for having our expectations met, is at the crux of a deep-seated need for normalcy. We have a limited capacity for taking in and processing information — we have limited short-term memories. When there is a flood of unfamiliar data, we get overwhelmed. We end up not having enough cognitive and emotional capacity to handle the new stuff on top of all the other things we have to do. Sudden change makes life feel overwhelming. Anchoring Errors This brings me to anchoring errors, which are basically little cognitive traps our minds…

What’s in a Cover?

by Olga Werby • August 7, 2018

The design of the cover can make the book… or so I was told. Certainly, bad covers don’t contribute to sales. But good covers are difficult. And the thought on cover design has changed over the years… just like fashion. Since I tend to design my own covers (and I’m an artist and a designer), I wanted to put together some ideas, if not rules, to follow and some background of how to think about book cover design. Because if you don’t do your own, you still need to communicate what you want with the person that does. Book Covers Through Time To appreciate a cover, it helps to understand its roots. I won’t go back far, since my genre is science fiction, just a hundred years or so. Consider the cover evolution of Jules Verne’s “Journey to the Center of the Earth”: There is a movement from frills to realism to a strong graphic look of the more modern editions. While for the 1800’s editions, we might find it difficult to identify the genre of this story, by the time we hit 1960s, there is no doubt that this is a science fiction or fantasy novel. The cover alerts…

Meditations on Blockchain

by Olga Werby • July 3, 2018

The internet is flooded with contemplations, broodings, and cogitations on Blockchain. One of the possible uses of this technology, Bitcoins and its ilk, has been the reverie, prayer, and speculation engine for endless get rich schemes and the constant fodder for media rumination. But what is it really? The direct answer is that Blockchain is just a digital form of trust. Allow me to walk you through it. Trust has always been the foundation of any society. Early on, when social groups were numbered in low dozens and basically consisted of associations of family members, trust was the currency among the members. You can trust your father-in-law because the survival of his grandkids was in his interest as much as your own, presumably. If a member of the family strayed, everyone knew about and punished the transgression accordingly, including by removing personal trust. But once the social groups grew in size, trust was more difficult to establish — who could remember who did what and to whom? To supplement trust born of personal knowledge, institutional trust was invented: laws, banks, governments, … and of course religious institutions. It no longer mattered if you were not familiar with a stranger, you…

Alternative Facts in Medicine

by Olga Werby • January 28, 2017

While we are collectively freaking out over the Trump’s White House use of Alternative Facts, these kinds of “facts” have been floating around in medicine (and politics) for a long time. And it is instructive to take a look at how we as a society have been dealing with Alternative Facts in Medicine and what damage these “facts” have wrought on us individually and collectively. I propose the following formula for how Alternative Facts come to be: Desperate Need + Greed = Alternative Fact Medical Myths: Beliefs Based on Outdated Science To start, allow me to refresh your memory, for our history is full of myths when it comes to our heath and our diseases. Let’s begin with a bit of bloodletting. Bloodletting is almost as old as our civilization. Thousands of years ago (that’s thousands, with three zeros!), a healer’s first choice of treatment was to let out the “excess” blood from a patient. Be it a migraine, an infection, or a virus, a person who was probably too sick to object was cut with a lancet or some other easily available tool and weakened even further via blood loss. The Greek physician Erasistratus believed all illnesses were due…

Cultural, Psychological, and Evolutionary Basis for Your Political Choice in 2016 Presidential Election

by Olga Werby • November 5, 2016

Who’s your choice for president this election? How did you make your decision? Given where you live and who you are, you might never really had a choice! Your vote might have been decided for you even before you were born… Might. Cultural Argument: Empathy versus Sympathy There is a lot of talk about the presidential candidates that start with: Who would you rather have beer with? Why does such a question have resonance? Why do we put so much importance on our ability to relate to the candidate? Why do we feel that our ability to visualize ourselves hanging out with a potential president somehow qualifies them for office? Many pundits and TV personalities try to convince us that it matters one way or another. But why does it work? Why do people believe them? Well, there is actual is a reason, and it just happens to be culturally-based. It is worth looking at another example that has nothing to do with people running for the Office of the President of the United States of America. Consider mental illness. How do you feel about a person with schizophrenia? How do you feel about a person with Post Traumatic Stress…

Hacking Weight-loss with Brain Science

by Olga Werby • February 18, 2016

Financial rewards for weight-loss and exercise work…but only if you take the money away at the end for non-performance. Rewards are just not as effective as punishments! [Study: Framing Financial Incentives to Increase Physical Activity Among Overweight and Obese Adults: A Randomized, Controlled Trial] This result is, of course, very consistent with Dr. Daniel Kahneman’s work in behavioral economics, memory, and our perception of happiness. One of the key points is how we assign value on items that we already owe versus those that we are considering acquiring. Consider your house (if you own one) or your car. Would you sell it for the same amount of money as you would be willing to buy it for? The answer is no! We value what we own far more than other people’s stuff. Our reaction to ownership is emotional. Mathematics of equivalence just doesn’t penetrate how we feel through to our judgement. Consider the following social incentive program: At the start of my weight-loss program, I get $50 to lose 10 pounds over a 6 months period. At the end of that time period, I only lose 4 pounds. I have to give back $30 — that’s the deal, right? I…
