This column http://tinyurl.com/hferhlcwas written in 2003, so hopefully Cecil has learned a bit. More specifically, learned that a tremendous amount was known about unconscious mental processes when he wrote that column.
Since my PhD is in Cognitive Science and my research focused on language comprehension in what is known as the “online” sense, taking measuring responses in differences of milliseconds during the reading process, we’ll go with language.
Learning a language is not the evidence for unconscious mental processes in humans: using language in general is almost entirely unconscious. When Cecil writes his columns, almost everything he does is unconscious. Learning to type is a process of turning a conscious series of behaviors - selecting the right keys to pressed to spell a word - into an unconscious series of behaviors. No more looking at the keyboard, hopefully a massive increase in speed from a dozen or so words a minute to many dozens.
If you’ve ever tried to learn another language, you’ve probably learned about all sorts of elements in that other language that differ from your first language. You’ve learned what they’re called, and you’ve tried to learn how to make these discriminations in your new language as automatic as that of your first language. That process makes you aware of just how much of the “grammar” of your language is not part of your awareness when you use your language. You had plenty of knowledge about how to use your language, but that knowledge was unconscious until you encountered a situation where you had to learn a different way of expressing things.
This was Freud’s lasting accomplishment. Plenty was known about unconscious behavior at Freud’s time, and for eons prior. Non-human animals could engage in complex behavior, and this was considered unconscious complex behavior (this status is somewhat debatable). But in Freud’s time, psychologists were rigorously studying the behavior of animals in various situations to better understand how learning worked. No one thought that the pigeon that learned to associate the red light with “food is coming” and the green light with “loud noise is coming” was learning anything in a conscious manner.
But Freud was one of the main influences leading people to recognize that their behavior was, in very many ways, as unconscious as those of a pigeon.
Now falsifiability. Freud did propose falsifiable hypotheses. One of these is central to Cecil’s column, Freud’s seduction theory. Freud hypothesized that many adult anxieties and other mental troubles were due to infantile sexual abuse. Freud discussed this with his patients, who in turn accused their parents of having abused them. Their parents rejected this charge of abuse to the extent that Freud and his patients believed those parents were truthful. This resulted in Freud considering his seduction theory to be incorrect, and he admitted so.
Hypothesis -> testing -> absence of supporting data -> rejection of hypothesis.
There are other elements of Freud’s work that have been presented in a falsifiable manner, and supported or rejected by Freud or others, or accepted in a revised form. Many of Freud’s mental defense mechanisms (displacement, projection) fall into the category of “sorta true”. But the specifics of a scientist’s theories are often revealed to be only sorta true over decades or centuries. Einstein (and others) determined that Newton’s laws of motion were sorta true, as others did with regard to his research on optics. On the other hand, chemists determined that Newton’s massive compilation of theories and evidence for his alchemical beliefs were essentially false.
So Freud is more defensible than many outside of the field of psychology give him credit for, and even experimental researchers on language know this.
Another area where Freud’s thoughts retain utility are his more anthropological writings, like those on religion expressed in The Future of an Illusion. A lot of it is in the sorta true category, but many people would be happy to contribute to science important information that is considered to be sorta true a century later.
