I don’t know if you are guilty of the p-word, but I was thrilled to discover that humans are not the only ones to do it:
Behaviorists developed an animal model of procrastination with implications for human work habits. When they trained a pigeon to press a lever for food and required it to press a high, fixed number of times before getting the food, it pecked slowly at the beginning of each series as if it were putting off the hard work it had to do. The scientists found that they could get rid of this slowdown by making the rewards more frequent, or by spacing them randomly. (115)
Even better, there may be an evolutionary advantage:
Procrastination has a long evolutionary history—even pigeons do it. Why should that be? Part of the reason is that procrastination is sometimes advantageous. Ancient Egyptians had two hieroglyphs that have been translated as “procrastinate.” One meant harmful laziness in completing an important task, such as tilling the fields at the appropriate time in the Nile flood cycle. The other hieroglyph denoted the useful habit of avoiding unnecessary work and impulsive effort. (117)

I am not surrendering my title as the greatest procrastinator in the world to any pigeon. At least, not today anyway, maybe tomorrow.
Ha! Since reading that passage about the pigeons, I’ve had this whole new respect for them. I see them crowding the sidewalk, pecking, slowly now that I am paying attention, and I think, “You are my kin.” This is a huge improvement over, “Move over, vermin.”
Pigeons are smarter than they look but it’s still hard not to think of them as vermin. Procrastination though, I am all for it!
What useful bits to know: thanks!
I find this neat too. Hope it interests you to check out The Procrastination Equation. Here’s an excerpt to highlight the common ground:
Animals might be our fellow procrastinators. After all, we share many other “human” personality traits with dozens of other species, from Rhesus Monkeys to Octopi. Wild Great Tits, for example, exhibit varying degrees of aggressiveness and risk taking, traits that enable greater environmental exploration. The bolder birds expose themselves to more danger but also reap the gains of better nesting places, food sources, and choice of mates. For another example, just ask any dog or cat owner if their pets have a unique personality; the owners will rightly insist that their furry friends differ in terms of affection, anxiousness, aggressiveness, and curiosity. Significantly, this list of shared traits includes impulsiveness, the cornerstone of procrastination. But this doesn’t necessarily translate into procrastination itself.
Not necessarily, but it does in the end. Might be able to get you a review copy. Let me know.
Thanks for this, Piers. Fascinating stuff. I recently learned about octopi that use coconut shells as tools.
