Attention Is the Scarce Asset in Every Portfolio
Contents
Trevor L Taylor, a Miami private investor and the founder of Fortius Capital, hosts Hard Truths for a Soft World, a show that turns systematic thinking on technology, comfort, attention and connection. The argument this entry makes follows from that habit of mind. Money that is lost can, at least in principle, be earned back, while attention spent on the wrong things is simply gone. Research in economics and finance suggests that focus, more than capital or information, is the limit that shapes most decisions.
Attention as an economic resource
Economics studies how a society allocates what is scarce. The Royal Swedish Academy of Sciences awarded Herbert Simon the economics prize1 for his research into how decisions actually get made inside organizations, and much of that work turned on the limits of human attention. Writing two decades later in Wired2, Michael Goldhaber pushed the point further. Information, he argued, is not scarce at all; it is overflowing. What is scarce and desirable is attention, and an economy built around it behaves differently from one built on material goods.
Why limited attention shapes choice
Simon introduced the phrase bounded rationality, the Stanford Encyclopedia of Philosophy explains3, to replace the assumption of a perfectly rational decision maker with a model fit for minds that have real limits. The Econlib profile of Simon4 summarizes the consequence. Because gathering information about alternatives is costly, and because the results of many choices cannot be known anyway, people satisfice: they do as well as they think is possible, often with rules of thumb that save the cost of thinking. A limited supply of attention decides which options are ever examined.
Inattention in markets
Financial markets offer a clean test, because prices record how quickly news is absorbed. Stefano DellaVigna and Joshua Pollet, in a National Bureau of Economic Research working paper5, compared company earnings announcements made on Fridays with those made on other weekdays. Friday news drew a weaker immediate reaction and a larger delayed one, and trading volume around Friday announcements was lower. The authors read the pattern as weekends distracting investor attention, and they found that firms tended to release worse news on Fridays, as if they knew.
The finding matters beyond earnings season. It shows that even professionals with every incentive to pay attention do not absorb information the moment it appears. Their focus rises and falls with the calendar, with competing demands and with fatigue. A price that adjusts slowly because people were looking elsewhere is a measurable cost of limited attention, and the same delay happens in any organization where important news arrives at the wrong hour and waits on a desk until someone has room to read it.
What catches the eye gets bought
Brad Barber and Terrance Odean studied the same constraint from the buyer’s side. Their paper on attention and investor buying6 found that individual investors are net buyers of stocks that grab attention: stocks in the news, stocks with unusual trading volume and stocks with extreme one day moves. Searching thousands of possible purchases is hard, so many people consider only what has already caught their eye. Preferences choose among the options, but attention has already decided what the options are.
Scarcity narrows the frame
Attention also contracts under pressure. Reviewing Sendhil Mullainathan and Eldar Shafir’s book on scarcity, The Guardian described7 how a shortage of money or time produces tunnelling: an intense focus on the need at hand and a loss of mental bandwidth for wider questions and longer term consequences. The Economist summed up8 the same book in one line: those with too little have a lot on their mind. The lesson for any decision maker is that a crowded mind sees fewer alternatives, exactly when alternatives matter most.
More information is not more insight
If attention is the constraint, adding information can make decisions worse. A Harvard Business Review feature by Paul Hemp9 put the tension plainly: the value of information in a knowledge economy is beyond dispute, and so is its capacity to overwhelm the people who consume it. Goldhaber’s observation that we are drowning in information points the same way. The scarce input is the focused hour that turns a report into an understanding.
Allocating focus like capital
The original essay behind this entry framed attention in portfolio terms, and the framing holds up against the research. Focused hours on one problem compound, because the tenth hour of study rests on the first nine, while scattered hours reset. What gets measured gets watched, so choosing what to track is choosing where attention will drift. Defaults set by others, from alert settings to meeting invitations, act like a manager nobody hired. And every commitment accepted withdraws focus from something else, which makes declining a request the same discipline as passing on a mediocre deal so capital stays free for a good one. The idea of opportunity cost applies to hours as directly as to dollars.
Two further points follow from the research above. Urgent requests usually belong to someone else’s agenda, and they arrive with a sense of necessity that rarely survives a day’s delay, while important work seldom announces itself and waits indefinitely if nothing protects time for it. And because attention determines the choice set, as Barber and Odean showed, a person who never sets aside unhurried time to look widely will keep choosing among whatever happened to be loud that week. Protecting a little quiet, unscheduled time is maintenance for the part of the mind that connects ideas and notices the option nobody was promoting.
A weekly attention review
Agreeing with these propositions is easy; acting on them takes a routine. The practical version is a short weekly review run in the spirit of checking a portfolio. Start by looking backward at where focused time actually went, since calendars capture meetings but rarely the long middle of the day. Then compare that record with intention: which few subjects deserved deep work, and how many hours did they receive? Finally, make one allocation change for the coming week and measure it the following week.
The method borrows from the same systematic temperament that shapes systematic investing: know where the resource goes, decide in advance where it should go, review the gap honestly and adjust. The adjustments look small from one week to the next and obvious over a year. Capital can be raised, borrowed or rebuilt after a loss. A season of attention spent on things that never mattered cannot be bought back, which is why it deserves at least the care given to money.
