When You're a Hammer Everything Looks Like a Nail

by Mark Suster on June 14, 2010

Over the years I collected (or thought up) a series of short-hand phrases to remind me of life’s lessons that are applicable to business.  One of my favorite ones is “when you’re a hammer everything looks like a nail.”  The definition is kind of obvious.  We’re all biased by our backgrounds and tend to put forward solutions that our backgrounds suggest to us.  It’s so common to go into meetings where somebody acts a certain way or has a certain point-of-view that leaves me thinking, “Hammer.  Nail.”

An example of the phenomenon from the non-tech world is surgeons.  A doctor friend of mine told me a long time ago that the credo of surgeons is “heal with steel.”  Of course if your profession is to operate on people you quickly look at situations as those that can be treated with an operation.  A plastic surgeon once saw me (I have a small scar on my face) and said, “I could fix that if you come into my office.”  It never occurred to her that I could care less about the small scar on my face.  I chuckled.  Hammer.  Nail.

To illustrate let me first start with a quick example that some of you may have previously seen.  Take a quick look at the image below of a young Parisian woman with black hair, a black necklace and a stylish feathery hat.  This was shown to a group of MBA students at the University of Chicago.  After seeing the image we were asked to describe what we thought a typical night for this young woman might be.  This group talked about how she was probably out late at night in the city, dining late, dancing and drinking.  She was a stylish and attractive woman about the town who was cosmopolitan, single and sophisticated.

The room erupted into a violent debate and people literally could not believe their ears that some people could be so stupid!  ” ‘Cosmopolitan?’  ’Woman about the town?’ ‘Attractive?’… Are you guys high?  This woman is clearly a sad grandmother who is not very attractive at all.”

The other side, ” ‘Grandmother? On what planet is THAT woman a grandmother?”

You’d be surprised how long the debate went on before people realized we had been duped.  See only half the room had been told she was a young, stylish woman.  The other half had been told she was a sad, old woman.  The “young” crowd saw a woman looking to the left with most of her face hidden.  The center image is a chin and the her left ear is just below the hair line.  The “old” crowd saw the “necklace” as a woman’s mouth.  What others saw as a chin they saw as a hooked nose.  And what the other crowd saw as a left ear they saw as the left eye.

That story always stuck with me.  Many of you have seen it before.  In fact, I wasn’t in the group duped on my MBA program because I first saw it in Steven Covey’s book, “The 7 Habits of Highly Effective People.”

The parable is the same.  In every meeting we go into we bring our “young woman” biases.  We’re sure that we’re right because we’ve been shaped by years of looking through a specific lens.  And obviously we meet other people who see things totally differently than we do and they’re not necessarily wrong.

How do I apply this in business?

I ALWAYS try to think to myself in meetings, “What hammers is this person carrying?  Why would they think the way they do?  What is shaping their world view?”  And I always try to put that into the mix when I’m looking at how they think about the opportunity at hand.

Then there is the opposite problem, which is me.  I obviously have my own biases.  Having raised too much money at my first company only to be buried under huge liquidation preferences and a huge board with divergent interests I have a bias for smaller funding rounds and capital efficiency.  I believe that this creates more opportunities for both entrepreneurs (who have more exit options) and for investors.  But I know it’s not the only model and some companies have created huge success because they’ve had significantly more capital.  Or when I see somebody who is extremely “salesy” in a VC meeting I often write them off too quickly.  ”Ugh.  That guy is never going to stop spinning.  I’ll never be able to believe a word he says.”

It’s hard to check your biases at the door and I often do not.  At a minimum I try to surface my biases in my own mind before reaching a decision.  And when I talk with my partners I often lead with my bias, “You know how I feel about somebody who brings in too many senior brass before they’ve figured out their business model.  And that’s what worries me about this deal.”  Or, “I love entrepreneurs like that.  That woman is really hungry to prove herself and her experience in running sales for ABC company will position her well for this company.” Or whatever my biases may be.  I try to make them explicit both so that I’m aware of why I feel how I do and also to give my partners the opportunity to argue against me.  It’s hard to argue against biases that aren’t explicitly raised.

In summary:

  • When you’re speaking with people try to understand enough about them as human beings to understand why they might look at the world in the way that they do.  You may not guess correctly but trying to draw implicit conclusions is certainly better than not thinking about it at all.  You may refine your views over time.  Or more importantly you may “test” your views by asking questions that may expose a bias (or refute a suspicion you had)
  • Try to be aware of your own biases and how they may influence your point-of-view on a topic.  To use the analogy in the post, be aware of whether you may be subjected to the “young woman” or “old woman” type of bias.

    Excellent thesis and a well written article Mark. I wrote a blog post a few weeks back on how the hammer problem applies to Yahoo's current challenges. Would love to know if you agree/disagree. Thanks much.

  • You pumped me to see the image as a beautiful woman- I'm having a hard time seeing it the other way.....
  • Ha. I struggled with it the first time, too!

    This is a favorite quote of mine as well, and I thought of it during my week at Babson's Symposium on Entrepreneurial Education. In a case taught about a medium-size gourmet coffee chain that was struggling to grow faster, the surprise twist was that building the brand was irrelevant to future growth, the mall-based chain's core customers were indifferent to brand, or even coffee quality. But, the entrepreneur, who had a marketing background, kept trying to solve the problems through new marketing programs rather than through operational cost reductions.

    More generally, the generic challenge of being an entrepreneur is gaining 360 degree vision when we all have particular areas of the business we're more comfortable with. So when there are problems to be solved (which is most days), the first inclination is to try and solve them from our respective areas of strength. Being wholistic is hard.
  • With ya and we're all guilty of it. I like to solve "from my perspective" but often that isn't what's best. It's why VC's sometimes need to stay out of the way.
  • Mark, have you read Cialdini's Influence? http://amzn.to/cZTFrL If not, I highly recommend it. If so, would love to hear your thoughts.

    Cialdini describes the "biases" you refer to as a "click, whir" response. People try to avoid making decisions by creating shortcuts for themselves. They have internal tapes they run which tell them how to respond under various conditions.

    I think you provide some useful advice for mitigating against automatic responses.
  • I read his other book. Been meaning to pick up this one. Thanks for the prompt.

    In a related vein to your suggestion of trying to understand the other person's world view, I picked up an explicit lesson from a friend who has taken several enterprises forward to success - leave the money discussion to the last, and focus instead on "what else" your counterparties want - more family time? more creative freedom? resources to do more interesting R&D? a quick close? a small on-going participation if their pet project is a winner? an assistant? Digging into these other motivators and desires first opens the door to relationships & transactions that have more parties committed to finding a "fair" compromise on the money, because they see significant personal benefit in other aspects that have already been discussed and offered.
  • Understanding all of the non-monetary motivators is certainly important and overlooked.
  • Good post, it's a cliche, but only because it "nails" an evergreen concept. ;-)

    It reminds me of another story that relates to how a CEO or principal has to make decisions. If I recall I read it in reference to the Bush administration. The plot line was roughly that Bush's defenders had claimed that as an "MBA President" he knew how to assemble a top notch team, and that his inexperience didn't matter as he had guys like Powell, Rumsfeld, etc, who were stone cold veterans, surrounding him.

    The counter I think came from good ol' Bill Clinton or someone associated I think -- saying that running the country is such a wide reaching and incredibly complex thing, that the *only* things a president ever sees are the really tough decisions, the ones where there isn't a consensus among all the deputies. If there was he wouldn't need to deal with it.

    Which is where the "hammer" analogy fits in. Regardless of the size of the organization everyone with a position player role comes with an agenda. Sales wants the product faster. Engineers want it perfect. Operations guys want costs controlled. You know the drill.

    (damm that second pun wasn't intentional...)

    Anyways. I would be interested to read your thoughts on what comes next. It seems to me that the mark of a really excellent leader is the ability to take in everyone's opinions and synthesize a working and coherent strategy. Which requires sort of adjusting for everyone's version of the "hammer" and discounting or revising perceptions based on the biases they have. While keeping everyone happy at the same time.

    Feels like a true leader is someone who can cut through all the biases in the room to get at the root of an issue, and be decisive and clear enough that everyone puts the hammer down and falls in line.

    Or, as you conclude -- someone who can rise above their biases and lead.
  • perfectly said. perfectly. that's exactly what leadership is.
  • Great post. One thing that occurred to me while reading this, is that repetitive bias we sub-consciously create can often act against us.

    Example: I've favored towards the financial side of business and I used to be 'coined' as a frugal person in executive meetings. And once I started to create this bias it immediately hit me my opinion sometime was pre-emptive and not well thought out.

    How I stopped? I forced myself to ignore my bias, no matter how strong. I made myself ask 1-3 well thought out questions before coming to any conclusion forcing myself to think more consciously about situation.
  • Yes, this is true. A bias can become a personal brand others apply to us so we need to be conscious of this. Thanks for sharing.
  • The hard part is when the hammer is EXACTLY what is needed, yet others don't see it.

    That balance between when the OTHER persons hammer is what is required and it doesn't feel right to you, is when it gets hard.

    Few hammers look the same.
  • The hardest part is when either hammer will work equally well, but both of you want to use your own hammer.
  • Another great blog post. I have referenced your work before, and I'm sure I will yet again. One thing about this metaphor, it's not going out of style anytime soon. I think it's great how you talk about both sides of the table. Your level of disclosure astounds me as you know you'll be in front of people who have read this post. 7 Habits was my first self-improvement book, so I'm partial to posts referencing it, as well!
  • Thanks, Jade. 7 Habits is the most influential business book I've read. You'll see 3-4 posts in the near future coming from it. Already planned.
  • Good read @msuster. People like us who follow you will read through it fully. But I wish the post were a bit shorter (kind of one pager) for readers who happen to stumble upon. The section titled 'How do I apply this in business' shouldn't be missed.

    On a tangential note, I am thinking of doing a post titled "When you are a nail, everything looks like a hammer' J
  • Yeah, I thought about putting that punch line more at the top. I should do that. And I always struggle to get the total words shorter. Oh, and it's Mark ... ;-)
  • What was I thinking when I called you Mike? Better to stick to addressing you as @msuster :) Edit done.
  • Srikanth Achanta
    i try to put myself in their shoes, imagine having the same background as the person speaking and then try to asses if that was a open minded answer or a "i know it better than you" answer.

    It usually works. :)
  • That's a great suggestion
  • Let's not underestimate the utility of a hammer and the effectiveness of a determined swing. Smack the thing a few times and if it gives, it might as well have been a nail ;)

    BTW, the quote is attributed to Bernard Baruch: http://en.wikipedia.org/wiki/Bernard_Baruch

    Great post, thanks for sharing.
  • Yep, very similar to what I was thinking. I've seen plenty of innovations occur when a technique from one arena is applied to a very different one.

    Being aware of the biases involved is probably wise (I wish I had the personal discipline to do that!), but don't dismiss the output simply because it comes from a fixed world view.
  • Great great great post Mark. These are things I try to keep in mind as well, but I've never had some so nicely organized before. I think the hammer and nail analogy will probably help me to keep this in mind when working with and meeting new people.

    It comes down to just proper personal communication skills, or just "people skills", without being some sweet talker / b.s. artist.

    Understanding your own biases along with being able to view and understand the biases in others is amazingly useful, but I dont need to tell you that.
  • Jayant Kulkarni
    One of the things that I have observed is that if you ask somebody experienced for advice they always give you the advice that they wished somebody had given them and not what is relevant to your situation.

    The way I work around this is by asking a lot of people for advice and synthesizing the suggestions. Somewhere in there is what works for my situation!:)
  • Sounds like a smart approach.
  • Roman Giverts
    Interesting post, but I think there needs to be a distinction between good biases and bad/wrong biases. Sometimes biases are good because they help you sift through the mess quickly, so to speak. For example, in the early stages of a hiring process when you're doing quick phone interviews, you don't always have the time to evaluate every person as objectively as possible. So you rely on your biases to make decisions on people a bit faster. It's not always fair to the person and you don't always make the right decision this way. But to be honest, more and more I'm trying to develop accurate biases to improve and speed up my decision my making process. Does that sound crazy?

  • It doesn't sound crazy and yes, biases cut both ways - positive and negative. You can never be right 100% of the time but it helps you to narrow your decision set.
  • JRVC
    Great point! However, when you are sitting around the table with your partners in a Monday morning meeting, how do you inform someone that they are relying on their "hammer" a little too much?
  • Trust me, it comes up all the time!
