Am I Saving Enough in an Emergency Fund?

This is the third installment in our series on how individual investors can assess their financial health.

DebtSurveys of consumer finances often conclude that American households have far too little—if any—emergency savings.  In a 2011 study by the National Bureau of Economic Research (NBER), 25% of Americans surveyed indicated that they had no way to come up with $2,000 within 30 days to cover an emergency—and an additional 19% concluded that they could only do so by selling or pawning their possessions or resorting to payday lenders.  The NBER study refers to such households as financially fragile.  In a 2013 survey, the Federal Reserve Board found that only 48% of people were confident that they could easily access $400 in an emergency.

A commonly-cited goal for emergency savings is to have six months of living expenses available on short notice. But the 2013 Fed survey found that 64% of people aged 45-59 and 42% of people aged 60+ had less than three months of living expenses available in the event of ...

Christian Rudder’s Dataclysm

Here’s what I’ve spent the last couple of days doing: alternatively reading Christian Rudder’s new book Dataclysm and proofreading a report by AAPOR which discusses the benefits, dangers, and ethics of using big data, which is mostly “found” data originally meant for some other purpose, as a replacement for public surveys, with their carefully constructed data collection processes and informed consent. The AAPOR folk have asked me to provide tangible examples of the dangers of using big data to infer things about public opinion, and I am tempted to simply ask them all to read Dataclysm as exhibit A.

Rudder is a co-founder of OKCupid, an online dating site. His book mainly pertains to how people search for love and sex online, and how they represent themselves in their profiles.

Here’s something that I will mention for context into his data explorations: Rudder likes to crudely provoke, as he displayed when he wrote this recent post explaining how OKCupid experiments on users. He enjoys playing the part of the somewhat creepy ...

The Genetics of the Schizophrenias

A new study sheds further light on the genetic basis of the group of psychiatric disorders known collectively as schizophrenia. Further, the study (actually a collection of four studies) takes a new approach that might prove generally useful in associating genetic variation with disease risk, even beyond psychiatry.

Schizophrenia

In popular culture the term “schizophrenic” is often used to mean split personality or multiple personality, but this has never been the actual definition of the term. I’m not sure what the origin of this misconception is. The word “schizophrenia” does mean “split mind” but refers to mental illness characterized by disordered or delusional thinking. The “split” is between reality and mental function.

For at least several decades it has been clear that schizophrenia is not one discrete disorder, but rather it is a set of similar disorders. Symptoms include hallucinations, delusions (persistent false beliefs that do not have a cultural cause), impaired reality testing, bizarre thoughts and behaviors, often but not always paranoid in nature, a disconnection between thoughts and emotions, and lack of ...

Creativity pie chart by James Clear

Creativity pie chart by James Clear

What separates the likes of Steve Jobs, J.K. Rowling, or Pablo Picasso from the rest of us? Over at Entrepreneur, James Clear argues it comes down to pure grit:

How do creative geniuses come ups with great ideas? They work and edit and rewrite and retry and pull out their genius through sheer force of will and perseverance. They earn the chance to be lucky because they keep showing up…

No single act will uncover more creative powers than forcing yourself to create consistently….For you, it might mean singing a song over and over until it sounds right. Or programming a piece of software until all the bugs are out, taking portraits of your friends until the lighting is perfect, or caring for the customers you serve until you know them better than they know themselves.

The Human Mold: Another Example of Self-Deception

This cover picture is scientifically inaccurate. See explanation below.

This cover picture is scientifically inaccurate. See explanation below.

José Jarimba believes that our bodies are physically molded into an asymmetric form by our mothers’ sleeping positions during pregnancy, that this has lifelong adverse impacts on health, and that shoe inserts can eliminate pain and other health problems by realigning the body. This is a silly untested hypothesis by a single individual. As such, it would be too minor to merit mention on SBM; but it is worth analyzing as a teaching opportunity. Jarimba attempts to bypass the scientific process; he provides a prime example of self-deception, confirmation bias, scientific ignorance, and the “Unpersuadables” I recently wrote about.

Much of alternative medicine originated with a “lone genius” who had an epiphany, thought he had discovered something no one had ever noticed before, extrapolated from a single observation to construct an elaborate theory that promised to explain all or most human ills, and began treating patients without any attempt to test his hypotheses using the scientific method. Some of them were uneducated laymen, others were scientifically ...

Ozy wishes you to know they wrote this in a very timely manner after Spandrell's original post and I just took forever to publish it.]

I made fun of this post on my tumblr and then Scott requested I actually argue with it.

First, let’s address the issue of homosexuality. Spandrell argues that “There’s no way on earth that a condition that makes you lose attraction towards the opposite sex is going to survive natural selection.” On the contrary, there is a lot of animal homosexuality. The linked book contains much fascinating information, such as the fact that animal sexuality has been documented in almost 500 species and that, in one study, ninety percent of observed giraffe sex was between two males. I am not sure why animal homosexuality is so common: I am not an evolutionary biologist myself. But it suggests that the simplistic model in which fucking something other than ...

A Brief Guide to Overcoming Instant Gratification

By Leo Babauta

It’s no secret that we live in the Age of Instant gratification.

That’s not news. But Paul Roberts has written an excellent essay at The American Scholar looking at the breadth of this phenomena on our society — it’s a must read.

A sample quote from Roberts’ essay:

‘The notion of future consequences, so essential to our development as functional citizens, as adults, is relegated to the background, inviting us to remain in a state of permanent childhood.’

And while he concludes that we need to change as a society, not just individuals, I’d like to show a path for individual change that might highlight a larger path for us as a whole.

This is a personal guide to overcoming the instant gratification to which we’ve all grown accustomed.

Why? What’s wrong with instant gratification — isn’t it true that You Only Live Once and that Life is Meant to Be Enjoyed?

Yes, life is meant to be enjoyed, but perhaps not wasted. Let’s take a ...

Stains the dog abstains from cupcakes on “It’s Me or The Dog” on Animal Planet

One of my favorite tropes in fiction is the idea of the perfect thinker – the person who has shed all the baggage of being an emotional human being and could enjoy the freedom and glory of pure logic, if only he or she could feel joy.

Spock, Data, Seven of Nine, Sherlock Holmes, Mordin Solus, Austin James, The T-1000 – there are so many variations of the idea. In each fictional world, these beings accomplish amazing feats thanks to possessing cold reason devoid of all those squishy feelings. Not being very good at telling jokes or hanging out at parties are among their only weaknesses.

It’s a nice fantasy, to imagine without emotions one could become super-rational and thus achieve things other people could not. It suggests that we often see emotion as a weakness, that many people wish they could be more Spockish. But the work of ...

Molly Crabapple: Make a Career That Fits You

crabapple black

In a time when old institutions are restructuring or collapsing, artist and writer Molly Crabapple urges individuals not to change who they are to be “professionally viable.” There is no longer a system you can enter and be set until retirement. Instead, she suggests creating a career unique to you.

…focus in on your weirdness, your passions, and your f***ed-up damage, and be yourself as truly as you can. Express that with as much craft, discipline, and rigor as you can; work as hard as you can to build a career out of that, and then you’ll create a career that you love and that’s true to yourself, as opposed to doing what you think other people want and burning yourself out when you’re older.

Don’t change who you are to fit the work out there — find that work that fits you.

Notes from the PA Longevity Prize

Last week I had the opportunity (thanks Alton!) to attend the launch event for the Palo Alto Longevity Prize. In short, it’s a $1m prize for substantial progress on “hacking the code of aging”. The Washington Post has more.

$1m is not a lot of money for this. But the hope is that by explicitly saying: “We want people to hack aging, and we will give anyone who does it a prestigious prize” it may attract key scientists already working on this, and also help legitimize the background assumption that aging *is* a disease which *should* be cured.

I have a lot of sympathy with this (h/t Nick Bostrom’s The Fable of the Dragon-Tyrant). I also see how curing aging could cause deep social problems. Some remarks I made in a facebook discussion:

I’m actually a little skeptical about the social effects of indefinite lifespan. Max Planck’s notion that “science advances one funeral at a time” is witty, yes, but I think it also largely rings true.

Stem Cell Transplant First

NeurologicaBlog is very meta. I like to not only communicate science, but explore how best to communicate science, including thinking about how to communicate the need to think about thinking. (Cue the endless meta-regression.)

For example, there is often much to criticize about how science news is reported in the general media. Part of the problem is that science mostly advances by accumulating baby steps.  Baby steps, however, don’t always make for compelling headlines, and so every advance becomes a “breakthrough,” every mystery has scientists “baffled,” and every study may some day lead to the cure for cancer, rid us of the common cold, or produce a piece of technology similar to that found in popular science fiction.

Part of the challenge of being a skeptical science communicator is to convey simultaneously the deserved awe of cool science, including the potential implications of genuine advances, while also discussing the need for caution in interpreting results, and essentially throwing a wet blanket on premature hype. It can be a delicate balancing act.

Public Speaking 101: Focus on Your Topic & the Words Will Come

Icon by Martin Smith from The Noun Project

Icon by Martin Smith from The Noun Project

A study from last year confirmed that many people find public speaking to be more anxiety-inducing than death.  As such, when practicing for client pitches, boardrooms and the stage, we often nervously prioritize style over substance by focusing on how to say things (your tone, pace, gestures, etc.) rather than what to say.

John Coleman suggests that we reverse our approach by focusing on what to say, not how to say it:

Focus on memorizing key stories and statistics, rather than practicing our delivery. If you spend your time on how to say something perfectly, you’ll stumble through those phrasings, and you’ll forget all the details that can make them come alive. Or worse, you’ll slavishly read from a PowerPoint or document rather than hitting the high points fluidly with your audience. If you know your topic, the words will come.

Trust your knowledge of the subject matter. Pick your key points and let the words find themselves.

Now you can work in your sleep

(Credit: iStock)

Parts of your brain continue to function when you’re sleeping, researchers at Ecole Normale Supérieure in Paris and the University of Cambridge have discovered.

They recorded the EEG (brain waves) of human participants while they were awake after they were instructed to classify spoken words as either animals or objects by pressing a button, using the right hand for animals and the left hand for objects.

Once the participants were asleep, the testing continued, but with an entirely new list of words to ensure that responses would require the extraction of word meaning rather than a simpler pairing between stimulus and response. The researchers’ observations of brain activity showed that the participants continued to respond accurately to the words (although more slowly) as they slept.

The study also extends earlier work on subliminal processing by showing that speech processing and other complex tasks “can be done not only without being aware of what you perceive, but [also] without being aware at all.” Sid Kouider of Ecole Normale Supérieure suspects that such unconscious ...

Medicine past, present, and future: Star Trek versus Dr. Kildare and The Knick

mccoyvs20thcen

I’ve been a big Star Trek fan ever since I first discovered reruns of the original Star Trek episodes in the 1970s, having been too young (but not by much!) to have caught the show during its original 1966-1969 run. True, my interest waxed and waned through the years—for instance, I loved Star Trek: The Next Generation, while Star Trek: Enterprise and Star Trek: Voyager pretty much left me cold—but even now I still find myself liking the rebooted movie series. In the original series, my favorite characters tended to alternate between Spock, the Vulcan first officer and science officer on the Enterprise, and Dr. Leonard “Bones” McCoy, the ship’s chief medical officer. I sometimes wonder if my love of these two characters had anything to do with my becoming a doctor and researcher myself. It probably did.

One aspect of all the Trek shows that always interested me was its portrayal of medicine in the 23rd and 24th centuries. After all, what doctor wouldn’t like to have a device ...
