High School GPA Predicts Future Earnings

    @Canuckguy You can type in anything in on Google and find research to back up your view. I am very skeptical that performing well throughout highschool is a precurser to a successful life. I personally got a low 2.- in highschool. Now I am currently maintaining a 4.0 with 21 units math/physics/chemistry while working. I go against everything this "research" you cited should predict.

    How well a student performs in high school is a function of intelligence? Sure we can both agree there is a correlation but that totally dismisses your income bracket and environment in which you work and go to school in. Black people overwhelmingly under-perform in high school but to say that it is a function of their intelligence is of course ridiculous. My point.. correlation does not prove causation. Your study is woo woo.

    Of course, one must use the caution in that educational decisions by the people in question were made decades (or even a century) ago, so financial "return on investment" of additional education may differ now compared to when the people in that study made their educational decisions. Over the past century, the educational landscape in the US has changed considerably.

    @RedEyeJedi‌ - You overstate the case considerably. No one said performing well in high school is a precursor to a successful life. The original study simply said that performing well in high school, on average, led to somewhat higher earnings in the next decade or so afterwards. Your anecdotal example means nothing, because no one claimed it was a 100% correlation or anything close to that. If you know statistics, you are probably familiar with a normal curve. For anything, even the most scientific (as opposed to sociological) circumstance, that means that even inputs at the low probability end of the curve have "successful" outcomes a certain percentage of the time. So it doesn't go against what the research predicts, you just beat the odds.

    I am also not sure who said intelligence was the only factor involved. In fact, I know I said, and I think others said or implied the same, that there are many factors, but intelligence certainly is an important one. The person said it was a function of intelligence, which doesn't rule out other factors in the functional equation. It is obviously a multivariate equation, with the weighting on certain variables changing with the stage of life, if you buy the research.

    I guess we see what we want to see. We live modestly in a high income area of Canada and the good professor was speaking to a predominantly white audience. I doubt very much he was thinking of minority students one way or another when that comment was made.

    What I got from the study is that future income is most highly correlated with extroversion, conscientiousness, and intelligence, AND in that order. In other words, intelligence is important, but extroversion is even more so.

    It also seems to suggest that being mean helps... Nice guys finish last?

    This is ridiculous. First of all, that's just obvious.
    Secondly, this is meaningless. This is sort of like saying "If you grow up in a poor neighborhood you're likely to be poor"
  • fallenchemistfallenchemist Honorary Super Mod Posts: 25,129 Inactive
    @TojoMojoWWII‌ - I think that while the correlation is fairly obvious, the point is that this quantifies it somewhat. Would you really have guessed that with that big a difference in GPA there would "only" be a 12% difference in earnings 10 years down the road? I would have thought it would have been larger. That is what academics do, they study details in many cases.

    High school GPA predicts or says nothing more that what it is. HIGH SCHOOL GPA.
    People get bought into all these causation, correlations issues that they will compare anything on the face of the earth.
    There many students that did not take high school seriously and thus ended up with low GPS, and then decided to wake up and end up with high GPA;s in college and v-versa. However, High school GPA is NOT the reason why they made so much money or are poor in life. That is solely a matter of personal choices.
    I mean, reports like this should be a given to just LOOK THE OTHER WAY. Look at the world around us, how many 4.0 GPA High school students are broke and living pay heck to paycheck, and how many 2.0 GPA High school students or dropouts are flying Private Jets and huge Savings?

    Well, that is kind of the point. On average, apparently, the 4.0 high school students are making more, and I would be willing to predict that more 4.0 high school students have huge savings than 2.0 students. Statistics never talk about individual cases, they simply represent the big picture. If you think that makes the study useless, then fine. You are more interested in individual cases. Other people like to see, with quantitative back-up, how people fare overall. If the correlation is weak, the percentage of people trailing out in the tail end of the curve, so to speak, will be higher.

    Don't act like the study claimed more than it did. Of course a lot of people get more serious about doing well after high school. Many don't. All the study is saying is whether it is because of motivation, organizational habits, intelligence, or some combination of these and more, people that do well in high school on average do better later in life than those that don't. No more, no less.

    If you think that is a trivial result, then OK. To a large degree I do too, and all I get from the study (and perhaps all it intended to accomplish) was to verify that seemingly obvious result and to have the gap quantified to the 12-14% range it reported, which is less trivial. After all, if a person with a middling GPA is thinking about spending $250,000 on college, they might take this result as an indication that they will be better off skipping college and start earning money right away. Or that they should go to a much cheaper school. But at least it is information to be considered.

    No.. I just think people are DESPERATE to find correlation for anything to feed their selfish goals or for publicity. Thus, some articles should not be written, let alone published and promoted.

    How does one calculate his or her GPA??
  • fallenchemistfallenchemist Honorary Super Mod Posts: 25,129 Inactive
    @coco2018 - That's pretty strong language. Are you saying the data is falsified? The researchers assembled the data and reported their findings. Why shouldn't the public be able to draw their own conclusions as to what the data really represents in terms of public policy? Do you really want me to list the number of great discoveries that were considered trivial or flat out wrong at the time they were made and reported? I am certainly not saying this finding is likely to fall into that category, but it might be useful data for someone in the future that has something much more impactful to report. I am not sure why you are so emotional about this particular piece of research.

    Don't believe everything you read.

    I also find it amusing that people seem to argue about a study that they only read about in an article. Did they actually go through the details of the study ? Do they have the experience to evaluate such studies in terms of methodology, applications of statistical methods, etc. ?

    Given how most high schools are nothing more than babysitters for parents while they are at work, I highly doubt that there is much correlation of grades to earnings. (BTW, the article doesn't even deal with the period of highest earnings for adults.)
  • fallenchemistfallenchemist Honorary Super Mod Posts: 25,129 Inactive
    @ManfromUncle - Exactly, the study is limited in scope, and I don't think the authors claim otherwise. I did look at the study in somewhat more detail, but certainly not a thorough or complete reading. And yes, I am quite capable and educated in research, statistics, methodology, etc. My own take is that people that get higher GPA's in high school are more likely to go to college (and my own take on that is that these people are more organized, more intelligent, and more motivated on average), complete college, and thus of course earn more money. As I have said several times, this is hardly breaking news. The only value I see here is that the study provides some quantitative data to the scale of that gap in earnings, and actually it is smaller than I would have thought. To that limited degree, the study, to me, has some value.

    People are getting far more exorcized about this than needs be. A simple study, mostly confirming what common sense and experience tells us, with a small twist of a slightly surprising (to me) smaller earnings gap than expected. And you are right, only for that rather narrow, yet very important, age slice.

    ^ Are you having any stakes in this article? Why SMH about the feedback from others. You can't sit to re-bottle every feedback that does not meet your own opinion about the article.
    I stand by my opinion, that the article is just NOT worth publishing...due to its irrelevance in the subject matter of correlation that its trying to emphasize.
