  • Are The Left Handers Smarter Than Right Handers?

    Are The Left Handers Smarter Than Right Handers?

    These and similar questions about left-handers are common but are they really true – Left-Handers

    The idea that left-handedness may be related to general intelligence (or any other cognitive ability for that matter) seems to be related to the fact that the origin of hand preference has little to do with the hands themselves.  Left-Handers

    Unless the person takes any action, it is impossible to judge whether a person is left-handed or right-handed just by looking at their hands.

    Left- and right-handed people’s bones, muscles, tendons, and other parts of their hands typically don’t show any noticeable differences. 

    Instead, the preference for using one hand over the other for fine motor tasks such as writing comes from the brain. 

    Therefore, it is at least conceivable that genetic or environmental factors that influence brain development in such a way that a person is left-handed may also affect the development of brain areas associated with intelligence.

    Are Left-Handed People Really Smarter?

    Accordingly, it is not impossible that left-handedness and intelligence are linked. But is it really so? Empirical studies show surprisingly ambiguous results. 

    Some studies find that right-handed people are more intelligent, while others find the opposite. Such differences between studies are not uncommon in the science of psychology and can often be explained by sample characteristics and specific methods used to assess hand and intelligence. 

    Therefore, it is difficult to determine the true effect by looking at individual studies.

    To finally settle the debate on left-handedness and intelligence, Eleni Ntolka and Marietta Papadatou-Pastou, two researchers from the University of Athens in Greece, conducted a so-called meta-analysis of published studies on left-handedness and intelligence (Ntolka & Papadatou-Pastou, 2018). 

    A meta-analysis integrates the results of several experimental studies, which has the advantage that the sample size is much larger, increasing statistical power and that the analysis is less likely to be affected by the sample characteristics of individual studies.

    Overall, Ntolka and Papadatou-Pastou (2018) integrated the results of 18 studies measuring full IQ scores in different hand groups. In total, data from 20,442 individuals were included. 

    Three meta-analyses were conducted on possible differences in standardized IQ scores between their groups:

    Comparison of left-handed people with right-handed people
    Comparison of left-handed and ambidextrous people with right-handed people

    Comparison of ambidextrous people with right-handed people
    Are Left-Handed People Smarter?

    There is no difference in average IQ scores between right-handers and non-right-handers, or between right-handers and mixed people. 

    There was a statistically significant effect for comparison between right-handers and left-handers, showing that right-handers have a higher average IQ than left-handers. 

    More importantly, this impact was very small and unlikely to have any significant real-life impact.

    Assuming that left-handers have an average IQ of 100 and both left-handers and right-handers have similar variation in their data, right-handers will have an average IQ of 101.05. Also, the effect lost statistical significance when a study was excluded from the meta-analysis.

    These findings led the authors to conclude that the absolute magnitude of differences in IQ between left-handers and right-handers is extremely small and that any intelligence differences between the two groups in the general population are negligible.

    So no matter what the fun fact sheets on social media tell you: Sorry Left-handers including me, we’re not smarter than the rest of the population in the world.

  • 5 Things Only Smart People Do

    5 Things Only Smart People Do

    What are the characteristics necessary to define a person as a Smart People?

    1. They know how to save

    Saving money is a concept that should not be confused with stinginess or greed.

    Intelligent people are at the forefront of those who are aware of this distinction.

    They know what it means to save money.

    Like some, they do not cut back on basic needs and spend on unnecessary things.

    For example, they use energy-saving light bulbs in their homes.

    They do not use credit cards, even if they do, they apply when it is really necessary.

    Before buying something, they think about how necessary that product is and avoid making arbitrary expenditures.

    They don’t get a magazine or Spotify or Netflix subscription.

    Because they know that they can access any information they want on the internet free of charge.

    2. They Trust On Themselves Not The People Around!

    Yes, smart people also have friends, family members, and business partners.

    But in any negative situation, they prefer to rely on themselves rather than others.

    So they know how to deal with problems alone.

    There is no task for them that cannot be overcome.

    Even if everyone leaves, people who can be successful alone are intelligent individuals.

    3. Wide Views!

    Intelligent people always avoid being rigid.

    They know how important it is to be open to innovations and think differently.

    They do not feel defeated because their thoughts or beliefs are wrong.

    Instead, they try to learn the truth and prefer to be happy for the value they add to themselves.

    4. They Don’t Focus On Mistakes!

    Smart people make mistakes too, yes! However, they focus not on the mistake they made, but on how to fix it.

    The main focus is That, it is not “wow sir, how did I make such a mistake”, but “how can I not repeat this mistake again?”

    This is how the strategies of successful companies work.

    As a result, if a lesson is learned from a mistake, that mistake will turn out to be more beneficial for you than harmful.

    5. They Know What It Means to Remember the Past!

    Unfortunately, a technology that will allow people to erase their past has not yet been invented.

    Therefore, it is necessary to get rid of this phenomenon of living in the past.

    Check how smart people have become adept at learning from their past.

    Because the past is gone by the name of the past. So there is no need to think about it at length.

    Intelligent people do exactly that.

    They always think tomorrow-oriented, and they do exactly what needs to be done today in order to be tomorrow-oriented.

    They know that clinging to the past will not help anyone.

    Conclusion;

    As you read, they are not very difficult things that smart people do.

    In fact, they are constantly doing the things that most of us are aware of and usually pay attention to.

    The secret to the success of many people and businesses is persistence and not giving up.

    In fact, that’s exactly what smart people do.

    They live by paying much more attention to the subjects and actions that most of us pay attention to from time to time.

    If you want to appear or be fully intelligent, you must constantly experience the 5 behaviours I have explained above.
