Study Shows Testosterone is Bad For High-Stakes Decisions

itwbennett writes "According to a study by researchers at the University of British Columbia's Sauder School of Business, young CEOs with higher levels of testosterone in their system are 'more likely to initiate, scrap or resist mergers and acquisitions' — even when it's not in their best interest. 'We find a strong association between male CEOs being young and their withdrawal rate of initiated mergers and acquisition,' says Prof. Levi, whose research relies on the established correlation between relative youth and increased levels of testosterone. 'For instance, young CEOs, who have higher levels of testosterone, tend to reject offers even when this is against their interest.'"

Of course, they are considered clever *after the fact*, by their results, but given that nobody knows the future and that most start-ups fail, it may be the case that the idea couldn't be too dumb, obvioulsy, but that probably it has more to do with luck and stubburness (a strange idea stubburnly pushed in the proper place at the proper moment) than with real cleverness (again, after the fact, the new ubermillionaire probably will tell you that "I knew from the begining", but before the fact, both the future ubermillionaire and the big pack of those that fail will probably tell you "this is going to be next boom, I'm absolutly sure").

      It's really not that simple. Money isn't cake, but you're treating it like it is.

      Suppose the game is played with cake, ie the two people split a piece of cake. After the game, the value for each player is the amount of cake obtained, and that value only depends on the player. There's an absolute amount of enjoyment from eating a piece of cake and that is not diminished if someone else eats a cake. In that case, even a tiny piece of cake is better than no piece of cake. The rational players will accept any split however unequal.

      But money's value depends on what both players do with it. For example, if the players are brothers, who both want to go to the movies. It is rational to refuse an uneven split (=> neither can go) rather than accepting (=> one can go). Another example: The players are neighbours, and the player with the biggest split can buy a bigger TV than the other. These are not like the cake example, as there's competition or status involved.

      Game theory is about placing a value on all the possible outcomes, not just one. You can't just arbitrarily claim that the only thing that matters is if the player is better off against his earlier self, that's just one outcome. In the cake example, that's the only outcome that matters because eating cake is an individual activity. But spending money is a social activity, so the value of the outcome must be measured against both his earlier self and the outcome for the other player.

      Your "Give me more than you" ultimatum results in a persistent loss for both, which is undesirable. Relatively you are no worse or better off. Realistically you are poorer.

      It's not undesirable if it preserves the status quo. Put differently, if both players agree on the 50/50 split, then nothing changes except inflation.

The game doesn't specify how many assets the players have and whether they are prepared to supplement the free money with their own savings. For example, imagine that each player is a parent whose normal budget is used up by feeding the kids, house payments, petrol etc. The players don't have $0.00 in the bank, but the winnings from the game is separate from their normal budget.

If the game was worth $200, its value would cover the price of a night out. Then the game would be who gets a free night out and who doesn't.

      Which is irrelevent. A Nash equilibrium doesn't have to do with equality between two people. It refers to the decision.

      And that's irrelevant. The payoff values have to encode the interactions between the two people in the first place, otherwise the game analysis doesn't model the game. My claim is that the absolute values $20 and $80 do not encode the interactions, therefore reasoning on them is the wrong way to analyse the game. A better way would be if the payoffs were written (-$30, +$30), or any other function of the split which quantifies the opportunity cost of foregone wealth.

      The player accepting $0.01 is better off accepting than rejecting, no incentive to change - condition 1 for a Nash equilibrium. The player keeping $99.99 has no reason to offer more (already accepted) and offering less will lead to rejection. No incentive to change - condition 2 for a Nash equilibrium.

      Wrong analysis. The second player has two strategies available: accept, whose payoff is unequal wealth and loss of competitiveness, versus reject, whose payoff is no increase of wealth while preserving the initial competitiveness. Accept is not part of a Nash equilibrium, because the increase of wealth being $0.01 does not overcome the loss of competitiveness due to the other player getting $99.99, so the second player has incentive to switch his strategy to reject.

      As you equalize the split, the Accept strategy becomes viable. When the second player is offered $50 or more, there is no loss of competitiveness any more and the wealth is increased, so that the second player has no incentive to switch from accept to reject, which would lead to no loss of competitiveness but no extra wealth. So Accept is part of a Nash equilibrium in that case.

      However, by symmetry, the first player gains wealth but loses competitiveness at less than $50. If his stragety is to take less than $50 for himself, then he has an incentive to switch strategies, taking a bit more for himself as long as the other player still accepts, which requires the second player to receive $50 or more. Thus, none of the strategies in which the first player receives strictly less than $50 can be part of a Nash equilibrium. The only remaining strategy that is actually Nash for both players is the $50/$50 split.

But being $20 ahead is still being $20 ahead. That $20 can still buy a meal, a DVD, or something else.

      The real point is that money encodes the potential for competition. This has nothing to do with revenge or fairness. In any situation where the two players have a social interaction where e.g. status is in play, the payoffs must include the loss of status from winning/losing or else the game analysis won't represent the real game. Let me give you two extreme examples:

      1) Two players, one lives in America, the other one is chosen randomly from the rest of the world, say China. The two players don't know each other, will never meet or live next to each other or buy goods from the same place etc. These two players are truly independent and there's no connection between them. The Chinese guy gets $80 and the American gets $20. They should accept, since in this case it's free money with no consequences.

      2) Two players, both live in the same city, they are good friends with the same interests and they would both want to buy the last ticket for a sports game. They play the game (essentially for the ticket) and the first guy chooses $80, ensuring that he can buy the ticket and the other one can't. Should the second accept $20, or reject? It's not obvious that he should accept at all. The consequences of letting the other guy take the ticket could easily outweigh the $20.

      And that's the problem: the payoff is not contained solely in the numerical value $20, the payoff is aactually a complicated function of the social interaction between the two friends. In the first example, there's no social interaction between the players, so the payoff simplifies to the numbers $80 and $20. In the second example, the payoff doesn't simplify to the numbers $80 and $20 alone.

      Now the first example is a special case of the second, where the interaction is nonexistent. Thus the second example is more general, and it cannot be solved by assuming that $20 is better than nothing. And this is specifically a money issue because money is a proxy for competitive behaviour: money is designed so that when a product is wanted by more than one person, then the price rises until the person offering more money gets to have it.

      So doesn't that mean that you are using an oversimplified model? I don't know much about game theory, but this sounds like something that is not a zero sum game, which means that there is not necessarily one winner and one loser.

      I would say that those who always accept $20 are using an oversimplified model, specifically by failing to take into account the competitive aspect of money in the payoff functions. If both aspects were taken into account, I would expect a continuum of equilibria within a neighbourhood of the 50/50 split but not too far off, with the Nash equilibrium nevertheless at 50/50.

    First of all it says "even when it's not in their best interest". This is a strange claim. CEOs are not supposed to make decisions that are in their best interest anyways, they are specifically supposed to make decisions that are in their company's best interest, and in particular, that best serve the shareholders of their company. To intentionally do otherwise would be reckless, not what they agree to do by becoming CEO, and could get them sued, nonetheless.

    Second of all what is in a person (or company's) best interest is subjective. To claim they are acting against their interest, you are applying prescriptive measures --- that they in your opinion should do certain things. For example "facebook should have agreed to merge with twitter". That is your opinion, which might or might not bear out.

    To cast a point of view about whether it was in their best interests or not is "in retrospect". In retrospect it is always easy to say someone should or should not have done that, knowing the outcome. Not knowing the outcome, it is not so clear, and they are CEO there, not you, which is presumably out of some merit.

    “We find a strong association between male CEOs being young and their withdrawal rate of initiated mergers and acquisition,” says Prof. Levi, whose research relies on the established correlation between relative youth and increased levels of testosterone.

    I sense a case of post-hoc ergo propter hoc here.

    Perhaps a better explanation would be, they are young, so they are as individuals less experienced, less wise, their age could have something to do with it.

    Also, the fact that they're male doesn't mean testosterone -- if a different pattern was observed in females, there would be other differences besides testosterone difference.

    You can't have an anecdotal study and have it be a legitimate study. You can't rely on knowing the fact that males of that age tend to have higher levels of testosterone and assume these groups of CEOs have higher levels of testosterone because they fall into that age category.

    If you drew blood, you might find a totally different correlation between these CEOs and low levels of testosterone. Without even sampling the variable you are trying to make claims about, this is not an experiment, and not science.

Some of which are quite common among people in my situation, others are more individual. It's hard to determine which changes are due to the hormones and which are merely due to feeling more comfortable with my body, but some are so common and well documented that psychiatrists and endocrinologists more or less assume them to be hormonal. There's always exceptions, and the effects are variable and individual, but the following is frequently described:

    Reduced sex drive
    Increased appetite
    A change in orgasmic pattern, moving it closer to that described by women
    Increased skin sensitivity.

    Once I needed to get my testosterone levels checked. My doctor had a doctor-in-training assisting that month, so they spent a lot of my appointment talking shop. The doctor said, "I have another patient who says that testosterone levels are higher in single men than married men - he reads stuff on the Internet - " (Here she shot me a funny look.) "and now that he's divorced, he's expecting a change. There's actually some data to back this up. The thing is, single men tend to be younger than married men, so their higher level most likely comes from that."

    I decided to remind her that not everyone reads the stupid parts of the Internet and said, "Ah, the wonders of mistaking correlation for causation." She seemed quite surprised.

  50. Underwear. Not Testosterone by bratwiz · · Score: 2, Interesting

    I think its all about the underwear.

    Women tend to wear silky, smooth underwear, or maybe nylon with some lace.

    Whereas men tend to wear itchy, scratchy old boxer shorts or briefs, which would naturally make anybody cranky and hard to get along with.

    So its no wonder that the young males were predisposed to making different decisions.

    Did any of the researchers factor out the difference in the underwear ???

    I think not.

    Clearly the research and all of its outcomes is totally biased, and the real answer is 'It depends.'

      It's been a few years since I studied this stuff, but if I recall correctly, every offer + accept is the Nash Equilibrium for the ultimatum game, even 100-0/accept (weakly Nash).

      What is the "real" game? Your original scenario seems to envision the ultimatum game on an island, or some kind of zero sum game (which ultimatum is not).

      Most economists would agree that it's fair to assume a utility function weakly increasing on income. Therefore U(x+n)>=U(x) where x is original pre-game income (even zero as your model suggests), and n>=0. Further, economists assume that we make a selection that maximizes our utility. With those two assumptions income = x+n is weakly preferred to x. The only way your model makes sense is with a jealousy/spite variable where U is weakly decreasing on the income of the other person. That may very well be a viable construct for a utility function, but your argument is replete with unstated assumptions.

      The "real" game is the game that's played by people. The mathematical game can be anything, as long as the payoffs are specified.

      Most economists would agree that it's fair to assume a utility function weakly increasing on income. Therefore U(x+n)>=U(x) where x is original pre-game income (even zero as your model suggests), and n>=0.

      Unfortunately that consistently fails the real world tests. Such utilities simply do not model human beings playing the game. From this review of empirical studies:

      The most important conclusion that falls out of this review is that players' motivations, which often are not the ones posited by traditional game theory (and neo-classical eco- nomics, in general), and their perceptions of others' motivations are of fundamental importance in understanding strategic interac- tion.

      Economists have proposed many ways to overcome the failure of U(x+n)>= U(x) in the ultimatum game (that paper gives some), but it wasn't my intention in these comments to advocate any particular one, rather to point to the underlying issue by way of some examples.

      The only way your model makes sense is with a jealousy/spite variable where U is weakly decreasing on the income of the other person.

      No, there's no need to interpret the decrease as jealousy/spite. T(original)FA is a study of CEOs in high stakes games. Such games have a natural setting which is no bigger than the market/industry in which the action takes place, so it's reasonable (imho) to consider strategies where the future actions of the major competitor(s) are explicitly incorporated in the payoffs. To take a slashdot example, in a game between Microsoft and Google, or a game between Microsoft and Apple etc, shrewd market tactics may well look like jealousy/spite.

      That may very well be a viable construct for a utility function, but your argument is replete with unstated assumptions.

      Fair point, but like I said, I'm not trying to advocate a particular alternative, but rather criticise the bits that fail empirically. It may be that such criticisms are better framed within a single alternative, but then again this is slashdot and there are diminishing returns to writing elaborate comments.

      At the graduate level of Economics, it tends to be all math. That's why I tend to think that way. It's obvious you have studied a fair amount of Economics.

      I don't disagree with the empirical data you cite. However, your original statements lacked any sort of mathematical precision, and "Nash Equilibrium" is a precise term. The statements you are making now are far more precise.

      Since I haven't done so yet, let me address your statements:

      it's quite rational to reject $0.01 when the other player receives $99.99, since after the game the richer player has more options available to spend money than the poorer player.

      It depends on what your definition of rational is. I think most economists woulds say utility maximization is rational behavior. Further, many would say income maximization is rational, all things equal. Therefore, you would have to get some utility from rejecting the offer for 100/0 not to be (weakly) Nash. I really don't understand, "since after the game the richer player has more options available to spend money than the poorer player."

      So it's irrational to offer less than 50, and Nash is at 50/50

      Only if utility from rejecting an offer is greater than utility from the extra $50. I think that assumption is unwarranted, generally speaking. If I recall correctly, there was an ultimatum game played with Japanese people where the splits were actually 40/60 in practice. Economists were close to 100/0 in practice.

      Again, my problem with your statements is how fast and loose you are with language in a social science that strives for mathematical precision.
