#unfiltered #94 Is Conviction Black and White?

flower, black and white

I’ve heard a collection of sayings around conviction.

“Do or do not; there is no try.” Yoda.

“Get to 70% conviction. 90% means you’re too late. 50% means you haven’t done your homework.” Keith Rabois.

“Do half-ass two things; whole ass one thing.” Ron Swanson.

But the one that stands out the most is: “You either believe or you don’t.” Which I’ve heard many an LP tell me on the podcast. But also across VCs I’ve met over the years. And in full transparency, I struggle with that. Theoretically it makes sense. Building 99% of a car still means you don’t have a working car. There are a thesaurus of synonyms alongside, “I just don’t believe in you.” We’ve all heard it.

“You were an amazing candidate, but unfortunately, the talent pool was really competitive and we decided to move on with someone else. But please do apply again for a job that may be a better fit for you.”

“It’s not you; it’s me.”

“We’re just in different chapters of our lives. And we deserve to meet someone who is where we are.”

“You’re too early for us.”

“You’re out of scope.”

“I just have too much on my plate now, and I just don’t have the bandwidth to focus on this now.”

“Let me run this by my hiring/investment committee/leadership.”

All that just mean “I don’t believe in you.” (But it makes me feel like an asshole if I said it directly to your face. And I don’t want to be perceived as an asshole.) Ashamedly so, I’ve used a few of these myself.

In the investing world, I wonder if there are varying levels of conviction. Phenotypically expressed in varying check sizes. In fact, we have terminology for it now. Core checks. And access checks, or discovery checks, or simply, non-core checks. A core check is a substantial position. A meaningful percentage of the overall fund size. At least 1%. But depending on the portfolio construction, it varies from 1-5% of the fund. A discovery check, on the other hand, is smaller. Oftentimes, less than 0.5% of the fund size. Dipping one’s toes into the water so to speak, as opposed to a headfirst dive or a cannonball to extend the metaphor.

But if conviction really is black and white, should there be varying levels of conviction? Is there such a thing as believing in someone, but only half as much? Or a third as much as someone else?

Moreover one of the greatest lessons we learn over time as investors is that we’re quite terrible, over large sample sizes, with predicting winners out of our portfolio. The three to five biggest winners that put you on the roadmap are often not our three to five “favorite” investments ex ante.

A really good friend of mine once told me (mind you, that both my male friend and I are heterosexual), “The conviction you have in someone to be your girlfriend is different from the conviction you have in someone who is to be your wife. You build that trust over time. And what you look for is different over time.”

So back to the original question: Is conviction black and white? Is there really only belief and disbelief? Is there such a thing as I kind of believe? Or I believe but…?

While I don’t have a black and white answer to this black and white question, I’m inclined to believe yes. It is black and white. It just depends where you put the bar. The bar for you to date someone is different from the bar for you to marry someone. The bar to approve an investment to return a $10M fund is different from the bar to return a $1B fund. And, the bar to invest in an asset in a power law-driven industry, like venture, is different from the bar to invest in an asset in a normally-distributed industry, like real estate or public markets. What’s black for one is white for another.

#unfiltered is a series where I share my raw thoughts and unfiltered commentary about anything and everything. It’s not designed to go down smoothly like the best cup of cappuccino you’ve ever had (although here‘s where I found mine), more like the lonely coffee bean still struggling to find its identity (which also may one day find its way into a more thesis-driven blogpost). Who knows? The possibilities are endless.
