This is a question I was considering whilst reading this recent paper by Dorsa Amir and Chaz Firestone on the origins of a well-known visual illusion (a preprint is freely accessible here). It is an issue I have often thought about, and about which I have always wanted to write something. It is a question that attracts the attention of most scholars who study human behaviour, and most scholars will have a particular idea as to what their “first principles” are when it comes to constructing a theory of cognition.
Where does one start from when building up an account of a given cognitive phenomenon, though? Are there any initial assumptions in this kind of theoretical process? I think it is fair to say that in most cases one’s first principles can go some way towards explaining what kind of theory one favours to begin with, though this is not always explicitly stated; an enlightening case in this respect is the study of language acquisition, as I shall show later.
Let’s keep to Amir & Firestone’s study for a start. The paper focuses on the Müller-Lyer Illusion, shown in graphic A below, taken from their paper, an illusion that goes back to 1889 and is named after Franz Müller-Lyer, who devised it. Why is it an illusion? Well, because the two lines are of the same length and yet one typically perceives the top line to be longer than the bottom line, even after being told that they are of the same length – and even after checking this is so with a ruler. The Müller-Lyer Illusion seems to be unaffected by what one knows about it, and thus would be a candidate for a perceptual process that is more or less autonomous – it simply applies because of how our visual system works.

Or does it? A typical rejoinder has been that culture can shape the way we perceive the world in rather significant ways, and as a matter of fact not everyone is as susceptible to the Müller-Lyer Illusion as the western, educated population that is usually tested in cognitive psychology labs (this cohort is sometimes referred to as WEIRD; google it). Indeed, many cross-cultural studies have concluded so, and as a possible explanation it has been argued that the Illusion arises in populations who have been brought up in carpentered environments, shown in graphic B above – lacking this background, the Illusion is not as robust. Thus, the Müller-Lyer Illusion would be a product of experience and its observers might just be the exception rather than the rule. Read more »



At a Christmas market in Germany, I told my German girlfriend’s mother that I masturbate with my family every December.
The File on H is a novel written in 1981 by the Albanian author Ismail Kadare. When a reader finishes the Vintage Classics edition, they turn the page to find a “Translator’s Note” mentioning a five-minute meeting between Kadare and Albert Lord, the researcher and scholar responsible, along with Milman Parry, for settling “The Homeric Question” and proving that The Iliad and The Odyssey are oral poems rather than textual creations. As The File on H retells a fictionalized version of Parry and Lord’s trips to the Balkans to record oral poets in the 1930’s, this meeting from 1979 is characterized as the genesis of the novel, the spark of inspiration that led Kadare to reimagine their journey, replacing primarily Serbo-Croatian singing poets in Yugoslavia with Albanian bards in the mountains of Albania.


The Paradise, Pandora and Panama Papers, exposing secret offshore accounts in global tax havens, will be familiar to many. They are central to the work of economic sociology professor, Brooke Harrington. She has spent many years researching the ultra-wealthy and several books on the subject have been the result. Her latest book Offshore: Stealth Wealth and the New Colonialism is a continuation of her research; it focuses on ‘the system’, the professional enablers who support and advise the ultra-wealthy and make it possible for them to store and conceal their phenomenal fortunes in secret offshore accounts.

I have been thinking about artificial intelligence and its implications for most of my adult life. In the mid-1970s I conducted research in computational semantics which I used in
At about 6:30 am, we pulled up to the Labor Ready office in the Central District. My friend – who for the sake of this column will be called Rick – and I were responding to a trespassing call: a woman who was asked to leave the day-labor agency office was refusing.
