what would you guys rate the iq of a chicken

[CarpCharacin]

It really is a quotient in the IQ test.

Not ones yielded by current tests. Scores are still labeled as "IQ" scores, but are standard scores rather than quotients, as I've already explained.

You are correct in pointing out that the IQ test has fallen out of favour when attempting to measure intelligence and that's because of the limitations of the test.

Tests of cognitive ability are still in wide use, but have evolved over time. I think it's fairly clear that I was only talking about mental age / chronological age x 100 falling out of favor.

Allow me to refresh your memory;

I suggest it would be fair when trying to establish the IQ of a chicken that the test would then become species specific. Perhaps I should have answered it depends on how smart the chicken being tested is.

I'm not sure if you saw the conclusion of my first post in this thread. Here it is:

So yeah, estimating the cognitive abilities of chickens with reasonable accuracy would require a test built for that purpose.

Nope, I'm not being disingenuous; I think it's fairly obvious I'm stating an opinion.

It is, but with knowledge of how testing actually works, it would be disingenuous to say things along the lines of these statements: "FSIQs are quotients, not standard scores", "they don't reflect general ability", and "they are irrelevant to the study of cognitive ability".

I can't help thinking that we are losing sight of the subject which was chickens.
It seems you and perhaps I, are more intent on demonstrating our intelligence, if applicable, rather than dealing with the intelligence of chickens.
I'm quite content being as thick as a brick provided I can persuade people that chickens are intelligent creatures.

The test is either the IQ test, or it is something else. Pedantic I know, but a background in science tends to make one irritable when something that was clearly defined at conception then gets obfuscated to encompass anything that may be remotely similar.
You could save yourself some typing by assuming that I know not only what an IQ test is, but am acquainted with some of it's derivatives.

For anyone who has had the determination to wade through the ego flexing posts, please do read the link I provided. It does suggest that our species (humans) have vastly underestimated the intelligence of chickens even if they can't do IQ tests due to lacking a thumb rather than the mental capacity.

Some batteries have adopted new names for composites but most haven't. I agree that it would have been better if a new name had been adopted more universally. Though word meanings obviously change over time, and nowadays "IQ test" is most commonly associated with instruments that employ standard scores.

I agree that they're intelligent, it's one of the reasons I keep them. It's easy for humans to justify treating other species poorly by dismissing them as unintelligent.

IQ. It stands for Intelligence quotient. It's not an absolute measurement. It's relative to data gathered on achievement at a particular age.
So, the first problem is there isn't an adequate definition of intelligence.
Next, any definition of intelligence should take into account the skill set and environment in which those skills are used.
We, humans, think we are intelligent and by the criteria we use, which is relevant to our skill sets, tend to make judgements on other species using the criteria that is applicable to our skill set.
If you could ask a chicken if humans are intelligent they may well consider us thick as bricks.
In the more recent past there has been a greater effort to try to measure intelligence in other species. Such investigations have provided some surprising results.
There are a few easily accessible studies on the internet now.
Below is a summary of a number of studies that makes interesting reading, especially if you follow the links and the bibliography.

Thanks Shadrach for sharing. I’ve been reading some, scrolling through a lot. But for those who dont want to read it: here is my conclusion.

The intelligence of a chicken can be compared to that of a human child. Some things are like the achievements of a 2 year old child (the ability to understand that something exists even when out of sight) and behavioural / social complexity and knowing different animals and humans can be compared to the intelligence of a 7 year old child.
