Sibling Rankings & IQ Factors

Click to Download

Studies show that the oldest child in a family typically scores higher on IQ tests than the children born after him or her. Each level down in birth order corresponds to diminishing IQ. In other words, the third-born scores lower than the second, the fourth-born lower than the third. Plus, the IQ-factor transfers over to academic aptitude.  The differences aren't huge, which should provide some consolation for those third or lower in the family line-up.

In contrast, younger siblings tend to be more extroverted, forgiving, agreeable, and sentimental than their older sibs. Some studies have found that younger siblings function better in social situations, are more independent, and enjoy risk-taking more. There's some evidence that younger siblings are funnier. The latest studies even show that younger siblings perform better in school, grade-wise, in spite of the lower IQ and aptitude.

    I do not believe this is true actually. I have 5 children and my youngest two have a higher IQ it seems to me than the first child.
    It may be true in some cases, but not in my family. Thanks

    Dr Barron, I am a 75 year old female with peridontal disease.
    I am ashamed that my teeth and gums have come to this, but the last time i went to the Dentist i was having the silver fillings removed and the white fillings put in it's place.

    I had a tooth that the Dentist told me he was in doubt about saving.
    He told me that if he could not save it he may need to do a root canal.
    I have had a heart murmer for many years and i told him i did not want that done, that if he could not save it by filling it then to pull it!
    He said okay! But he went ahead and distracted me by talking to me about something else while he proceeded to do the root canal.
    I did not know till later that he had done that and was very disappointed in him for doing me that way. I have been through a lot in life with having to have two lung surgeries because of getting a fungus on my lung.[aspergillus]but i came nearer to dying after that root canal than i ever have in my whole life.
    So because of that i have been afraid to go back to the dentist again.
    I've stayed away from dental work since then, and that's been 10 yrs.
    I have teeth pulling away from the gums. They do not bleed or hurt me, but my gums do get sore from time to time. I feel sure that i'll lose some teeth because of this, and my heart problem has worsened also.

    I have several health problems and no doubt this gum disease will shorten my life, but i am reluctant to trust money hungry people again.
    I am holding a mixture of half water/half peroxide in my mouth and swishing before and after brushing.

    If you have any advice for me i would surely appreciate it.
    The article about the sesame oil was very impressive, but i don't think i would be able to do that for 20 minutes., but may try it anyway. I'm grabbing at straws at this point! Thanks so much. Etta
