Welcome to the Jungle

New York City, 1968. Busy street. A group of people have stopped on the sidewalk to look up at a window on the 6th floor of the adjacent office building. No one is in plain sight. No one is trying to make a jump. Nothing. A crowd is forming on the sidewalk. In fact, a crowd is forming at a surprisingly high speed.

When a group of 15 people or more stops to look up like this, 40% of passersby will join in even without knowing “what we’re looking at.” Psychologists, Milgram, Birkman, and Berkowitz conducted this experiment (“Note on the drawing power of crowds of different size” in Journal of Personal and Social Psychology, 1969) nearly 50 years ago, and its results have been confirmed several times since. Our propensity to conform and follow the crowd increases with the size of the crowd.

A JOKE (?)
Two men are in the jungle when they see a lion running towards them. Frantically, one of the men starts putting on his running shoes. Surprised, the other man says “What are you thinking, you can’t outrun a lion!” The other replies: “I don’t have to outrun the lion… I just have to outrun you.”

As cynical as it may seem, being a part of a herd is a brilliant survival tactic for any prey animal who cannot outrun its predator. We can even take it one step further; if you are quicker on your feet than the one running next to you, the best strategy is not even to divert from the herd and try to out-manoeuvre your predator, rather, you should follow the herd and trust that the predator will follow too.

This herd mentality runs deep in all of us. Especially, in the face of danger and uncertainty we follow troop. Even when what’s at stake is far less critical than in the joke above. When you leave a restaurant because it’s empty to stand in line for the one next door, you are tapping into your herd mentality: There must be a reason this restaurant is empty; someone else must know something; if I mimic the actions of others I don’t have to know why this decision is the right one! Of course, herd mentality exposes us as well, and our history is full of instances where collective actions are horrifying and downright inhuman (?)

Finance and crowds

In financial markets we don’t always see the actions of others, but we do see their impact on prices. The concept of financial speculation (such as day-trading) is built on the premise that you can profit from following trends as long as you are quicker on your feet than the rest of the followers. This can in extreme cases result in what economists call speculative bubbles; prices that get inflated and in turn burst because of the huge disconnect between price level and the underlying economics. This is equivalent to the point where the crowd on the sidewalk in New York suddenly decides to leave… it happens instantly because everyone has been waiting for someone else to make the first move.

In context of (investment) crowdfunding, the concern about herd behavior is particularly grave. Startup investing (and private placements in general) are risky, and the due diligence is more or less left to the investor. For that reason, herd behavior, speculation, and manipulation are central to the discussion.

In “Crowdfunding: Geography, Social Networks, and the Timing of Investment Decisions“, professors Agrawal, Catalini, and Goldfarb find that funding propensity increases with funding levels; i.e. a campaign becomes attractive when others have found it attractive. This is not to say that it is attractive because others have found it attractive, but simply that the timing is such that you as a fundraiser will have a simpler task once you have traction.

There are a couple of important questions to ask in this context, so I reached out to Prof. Christian Catalini, from the MIT Sloan School of Management, to learn more about how herd behavior impacts investment decisions.
