3 Questions That Will Get Your Finances — and Life — on Track
3 Questions That Will Get Your Finances — and Life — on Track
Question One: I want you to imagine that you are financially secure, that you have enough money to take care of your needs, now and in the future. The question is, how would you live your life? What would you do with the money? Would you change anything? Let yourself go. Don’t hold back your dreams. Describe a life that is complete, that is richly yours.
Question Two: This time, you visit your doctor who tells you that you have five to ten years left to live. The good part is that you won’t ever feel sick. The bad news is that you will have no notice of the moment of your death. What will you do in the time you have remaining to live? Will you change your life, and how will you do it?
Question Three: This time, your doctor shocks you with the news that you have only one day left to live. Notice what feelings arise as you confront your very real mortality. Ask yourself: What dreams will be left unfulfilled? What do I wish I had finished or had been? What do I wish I had done? What did I miss?

Black box auditing is fine
Black box auditing is fine
Last week I read this paper entitled “Black-Box Access is Insufficient for Rigorous AI Audits” with some excitement, since I do black box algorithmic auditing at my company and I was looking forward to knowing what more I could do with even more access. Also, it was written by a bunch of smart people from MIT, Harvard, Northeastern, Stanford, and so on.
But I’m not very impressed! Actually I think this paper is a weird result of what happens when academics write about stuff that mostly happens outside of academia. In particular, and I’ll skip a lot of things, I want to focus on their section entitled “Limitations of Black Box Audits,” because of the five bullet points they include, they are all wrong. I’ll just go through them one by one:
1. Black-box methods are not well suited to develop a generalizable understanding.
Their argument here is that you don’t understand weird inputs that could lead to strange behavior. They argue it causes the black box auditor to rely on heuristics. But that’s not at all true! When I audit algorithms, either with private companies who provide the data, or follow my instructions, or with regulators or enforcement agencies that insist on the data from the companies deploying algorithms, we always use all of the historical data that we can get our hands on. In other words, we do not rely on heuristics or synthetic inputs, we instead see how actual people were actually treated by these systems. This is a much more thorough black box audit, and it doesn’t require “understanding,” which I think is a misleading and unattainable goal; even the coders don’t really “understand” algorithms (just ask them).
2. Black-box access prevents system components from being studied separately.
Yes, that’s true! And no, that’s not a flaw! Audits are not supposed to identify where things go wrong, they are supposed to decide whether something is going wrong. From the perspective of an auditor, if certain stakeholder groups (say, black patients in the case of Optum) are being treated badly, then that’s the point of the audit. The question of what exactly went wrong and when is the problem of the folks who set out to fix the problem, but they are not auditors.
3. Black-box evaluations can produce misleading results.
The example they give here is that an algorithm can pass statistical tests of non-discrimination but still have underlying flaws in reasoning. But I’d argue, as an auditor, we don’t actually care what the underlying reasoning looks like as long as it *consistently* passes the discrimination tests! Of course, it’s likely that there should be a battery of tests rather than just one. I’m happy to talk endlessly about how to design such a battery.
4. Black-box explanation methods are often unreliable.
Yes, true, but that’s because explanations of algorithms are almost always nonsense. I’d suggest you stop trying to understand “how an algorithm thinks” and start testing whether an algorithm is causing meaningful harm to stakeholders.
5. Black-box evaluations offer limited insights to help address failures.
True, but again, not a problem! If you want to be an engineer paid to fix problems, don’t call yourself an auditor. Indeed there would be a conflict of interest if that were the same job, because you’d be incentivized to find problems to fix, or to only find fixable problems, etcetera.
If one of the authors of this paper wants to discuss this with me, I’d be more than happy to. We could even have a public conversation, since I live in Cambridge!

Consequences
Frederick Lewis Donaldson created a list of seven social sins that was soon popularized by Gandhi. One hundred years later, it’s more relevant and more urgent than ever.
Wealth without work.
Pleasure without conscience.
Knowledge without character.
Commerce without morality.
Science without humanity.
Religion without sacrifice.
Politics without principle.
When we create these imbalances, we pay for them.

“We used to do that”
When electricity came along, there was a swath of industries that were trapped in an old way of thinking. The only ones that thrived were able to walk away from what they used to do and eagerly embrace something new.
When the internet was young, the major book publishers had everything they needed to create a dominant search engine. After all, they were in the business of organizing the world’s information. With just one exception, they didn’t even consider it. That’s because they believed that their job was to sell books to bookstores.
This is even more urgent for individuals. What you were trained to do, what you did yesterday… that’s a gift from your past, not an obligation. Beginning the analysis with, “what I used to do was…” is a great way to open the door to what you’re going to do tomorrow.

Understanding Consciousness Goes Beyond Exploring Brain Chemistry
Understanding Consciousness Goes Beyond Exploring Brain Chemistry
The science of consciousness has not lived up to expectations.
Over the summer, the neuroscientist Christof Koch conceded defeat on his 25-year bet with the philosopher David Chalmers, a lost wager that the science of consciousness would be all wrapped up by now. In September, over 100 consciousness researchers signed a public letter condemning one of the most popular theories of consciousness—the integrated information theory—as pseudoscience. This in turn prompted strong responses from other researchers in the field. Despite decades of research, there’s little sign of consensus on consciousness, with several rival theories still in contention.
Your consciousness is what it’s like to be you. It’s your experiences of color and sound and smell; your feelings of pain, joy, excitement or tiredness. It’s what makes you a thinking, sentient being rather than an unfeeling mechanism.

Know Yourself Better by Writing What Pops into Your Head
Know Yourself Better by Writing What Pops into Your Head
The exercise of writing down unfiltered thoughts enhances self-knowledge
For decades, physician and author Silke Heimes has been leading groups in therapeutic exercises to put thoughts and feelings down on paper. Heimes, a professor of journalism at Darmstadt University of Applied Sciences, points to abundant evidence that writing for five to 20 minutes a day can improve health, diminish stress, increase self-confidence and even kindle the imagination. A writing routine, she argues, is a form of mental hygiene that almost anyone can benefit from.
So how do you start? What happens if—as every writer fears—the page remains blank? And how do you get rid of an overcritical inner censor? Heimes, director of the Institute for Creative and Therapeutic Writing in Darmstadt, explains how to overcome inhibitions and open up your inner world...

The unsurprising confusion about ‘per capita’
The unsurprising confusion about ‘per capita’
A car cut me off on the highway the other day. The car was going nearly 100 mph.
Was the car a new Porsche 911 GT3 or a used Toyota Camry?
The thing is, there are more than 1,000 times as many Camrys on the road. But our instinct is to pick the vivid and distinctive answer.
The per capita crime rate in rural areas is often dramatically (sometimes five or ten times) higher than it is in most cities...
