    Amazon Mechanical Turk (mturk) workers are highly educated - sources

    "We also asked the Mechanical Turk workers to declare their educational level. In general, the (selfdeclared) educational level of the workers is higher than the general US and Indian population. There are two factors that may contribute to this. First, many of the workers are younger than the overall population and, ceteris paribus, this leads to higher educational level. Finally, while we may not necessarily discount the possibility of false disclosure, there are no incentives that would bias workers towards lying in this survey."

    India: ~64% Associates degree or higher

    I find turking fascinating, you have a mixture of talents that can be accessed. I have had HS and 2 yrs vocational training in electro-mechanical technology (of course this was 300 yrs ago lol), we have all been exposed to the school of hard knocks, so we all have something to contribute even though we have not had higher education ,I think people that turk do have a higher IQ (I could be prejudice) who else can think of 25 ways that a cup makes them, happy, sad, anxious, and nervous.

    It is like dog grooming (yes I am a professional pet stylist) some folks think we do this job only because we are too stupid to find a REAL job, not true, I know groomers that are lawyers, doctors ect,,,,, So thanks for that post spamgirl, it gives us ammo to use against prejudice.

    I also believe. as I become more proficient in one task, that I can easily move on to the next type of task, where else can a person do that? one minute I am taking a survey on economics next I am doing receipts, how many of us if we do not know a answer to something later on google it, to learn even more adding to or knowledge and IQ, (where was I going with this post lol)

    Thanks spamgirl.

    Thumbs up

    Interesting...

    Appears some found US Turkers more educated and some found Indian Turkers more educated.

    IMO, although educated, success at Turking has more to do with self discipline and commitment than education. No one needs to be a scholar to enter receipts, perform transcription or most of the majority of the tasks available to the average Turker. However they would have to have the qualities needed to supervise themselves and stay productive and cost effective in an unsupervised and often distracting and chaotic environment.

    It is probably likely that a more educated worker pool would also be a more disciplined pool simply because one generally has to be more disciplined to complete a reasonable college curriculum.

    It's probably not news to most here that we as Turkers are generally a more intelligent and creative thinking breed.

    I will definitely hang on to this information and share it with the associates of mine that seem to have a different view.
    Cheers,
    Babarous

    I'm trying to keep it updated as I find studies that cite educational background.
