Recording Sensations

How much hard drive space would be required to record all the sensations that we experience in a day?

The most natural way for humans to store an image is an array of intensities red, green and blue values.  This makes sense because our eyes have sensors (cones) that have a peak response to red, green and blue light.

The most natural way for humans to store sound is two arrays of frequencies.  This makes sense because we have sensors in each of our ears that respond to frequencies of pressure.

I think the most natural way from humans to store taste is a five dimensional array of flavors for the intensities of sweet, sour, bitter, salty and umami.  But maybe there would also need to be spiciness and even the temperature of the food?  Has anyone ever tried to record a taste and replay it?

I’m less sure about smells.  I think every smell is a different chemical reaction in our nose, so it seems like the best way to describe a smell would be a long list of the intensities of various chemicals.  But maybe there is a hidden deeper structure.

I wonder even more about touch.  Surely to fully describe all the touch sensations in a moment in time you would need to record temperature and pressure everywhere in the body.  I’ve read that the feeling of wetness is just the feeling of cold plus light temperature and that it’s surprisingly easy to trick the body into feeling wetness with cold light pressure.  What about itchiness and numbness?  Is the heat from a rash the same feeling as heat from a stove?

I am the most unsure about internal sensations.  Is there one kind of nausea or many types?  I think I can imagine at least two.  One kind of headache?  What about tiredness?  Intoxication?

And does it even make sense to include feelings in this discussion?  Certainly we recognize a common set of feelings such as happiness and anger and we know that we can combine them in different ways.  We can even combine opposites – I think that it’s possible to be happy and sad at the same time, which means they would have to be recorded separately. 

Even if you add up all the different smells and internal feelings, I think recording all of the light that hits our eyes might be more data than all of the other sensations combined.

Go and the Beauty of Efficient Resource Allocation

One thing that Go players learn quickly is a visceral, aesthetic appreciation for an efficient allocation of resources.

Even a beginner would recognize the black stones in the first diagram as beautifully placed.  It is the minimum number of stones to securely enclose the White group in the upper left.

The third diagram adds yet another stone and is an even stronger shape in practice, but it is such an inefficient allocation of stones that it would never occur in a real game.

If only it was this easy to tell if a company was allocating resources efficiently.

Metrics and Hiring

Virtually every CEO claims to be extremely metrics driven.  As far as I can tell all of these CEOs are completely full of shit, at least when it comes to their own hiring.

We all hire based on intuition but we rarely go back and rigorously check our mistakes.  In my career, I’ve hired or been part of hiring 129 people that I know or remember well enough to confidently grade their performance.  Before last weekend, not once had I gone back and looked at the data.  Of course, that hasn’t stopped me from having strong opinions about interviewing and hiring.

HireData5

So I went through and labeled every hire on a scale from disaster to superstar.  I was involved to different degrees in every hire, but unfortunately I don’t have notes on the process that happened for each candidate.  The distribution of hires was about what I expected.

Next, I labeled the referral quality on a three point scale from unknown (0) to close friend (3) and the school quality from unknown (0) to ivy league (2).  I looked at the average school quality and referral quality for each type of outcome.  The results of my unscientific survey were striking and statistically significant.

Quality5

Referral quality was incredibly important – the eight worst hires that I’ve been involved in were all unknown to me and everyone at the company at the time of hiring.  Digging into the data showed that employee referrals were basically as good as my own personal referrals.  The average hire was a “might hire again” but the average employee or personal referral was a “definitely hire again”.

School quality was also positively correlated with performance, which was a surprise to me – I’ve always felt that people tend to overweight school quality in hiring decisions, but the data says that I probably underweight its effect.

Ask for Stories, Not Advice

People have a deep, intrinsic need to feel heard.  I’ve found the best way to charm anyone is to ask for advice.  This is especially effective with old men, who generally control the most resources.  Hence the old adage “Ask for money, get advice.  Ask for advice, get money.”

Paul Buchheit describes the fundamental problem with advice well, “Limited Life Experience + Overgeneralization = ADVICE”. 

As a first time founder, I was inundated with unsolicited advice.  Now I’m inundated with people pretending to ask for advice when they really want my money or introductions to people with more money.

My angel investor/mentor Travis gave me the most memorable advice I ever got: ask for stories, not advice.  Stories are much more fun to listen to and more fun to tell.  The listener can draw their own conclusions.

Purchasing the Feeling of Being Present

Why do we overpay for speaker cables, cheese, watches and virtually every luxury good?  It used to be a hobby of mine to see if people can tell the difference in blind comparisons between cheap A/V equipment versus expensive A/V equipment or cheap beer versus expensive beer and I will tell you from doing this many times that every single one of us massively overestimates our ability to tell the difference between cheap stuff and expensive stuff.  I’ve made a ton of money betting against people whether or not they can tell the difference between things like aerated and non-aerated wine.  It always goes the same way: when you tell people which is which they’re sure that they can tell the difference, and then the second you take away the labels they have no idea.

In college I saw an art history major who should have known better earnestly asked if a slide was a gesture drawing done by the previous beginner drawing class.  She was mortified to hear that it was actually one of Rodins famous sketches.  As a pretentious undergrad and a big Rodin fan I laughed at her but honestly I can see how anyone could make that mistake.

If you think that there’s something intrinsically and objectively better about fancy wine or fine art, you’re empirically wrong, but I wont try to persuade you of that anymore.  Experiments show over and over that people can’t tell the difference between cheap and expensive wine, but this study that showed that people enjoy wines  far more when told that they are expensive made me decide to shut up and try to enjoy luxury goods.

Why do we enjoy scarcer stuff more?  I’m convinced that it’s because it pushes us to be present, which is really the best feeling in the world.  We eat the local, organic vegetables slower and actually look at the fancy furniture we bought.  These days, I’ve stopped engaging my contrarian instinct to prove people wrong and started enjoying what I’m paying for: the pleasure of actually experiencing what I’m paying for.

Marketing an Early Stage Startup

Screen shot 2013-10-17 at 1.43.09 PMWhen you’re a tiny company, marketing feels really hard.  Compared to your well-funded competitors, you can’t afford ads, you can’t get press to talk to you and SEO probably isn’t working very well yet.  But there’s one thing that’s easier for you than your competitors: building a great brand.  All you have to do is follow your intuitions and ignore everyone around you.

Customers don’t ever want to feel like their dealing with a corporation, they want to feel like they’re dealing with a person.  Your big competitors who have a marketing team ghost-writing boring, soulless spam from the CEO, and have to run every blog post through legal, struggle endlessly for this consistency.  Unlike them, you can effortlessly speak with an authenticity that everyone will feel.

When I started CrowdFlower we had a blog that I honestly felt guilty writing.  I loved crowdsourcing and I loved crazy experiments.  Smart advisors told me to get rid of the blog, it was unpolished and distracting.  If CrowdFlower was their company, their advice would have been right.   The blog was unpolished and distracting, no surprise since I was unpolished and easily distracted.  But I knew a lot about crowdsourcing and I cared a lot about practical visualization and good statistics – things that were important to our customers.

Over and over I heard how much our customers loved it – and not just the startups of the world.  Multiple VPs from major financial services companies have said it was the cutting edge feel of our blog that ultimately convinced them to work with CrowdFlower.  That crazy blog, by itself, drove millions of dollars in revenue and was crucial in landing our first customers.

Your parents will complain that your copy is unprofessional, famous angel investors will tell you that your logo sucks, well-meaning customers will call you up and suggest changes to your messaging.   This feedback is valuable, but you should ignore most of it.  Ask yourself: do I think my logo sucks?  If so change it.  Otherwise, leave it alone.  Remember: strong negative reactions are usually a sign that you’re on to something.

Good, authentic marketing will only get harder from here on out.

Shout out to Demian Rosenblatt, who designed our logo and planted all of these ideas in my head, although I wonder if he will agree with what I wrote :).
