Topic: Will fish-oil pills make a child a genius Topic: Will fish-oil pills make a child a genius? Reading: Goldacre, Ben (2008). Bad Science, (Chapter 8, Pill solves complex social problem, 136-160). Group 5: Shu Min, Yan Ling (Presenter), Yi Mou

Outline Fish-oil case study Problems Outcome of study Implications of misleading data Conclusion

Will fish-oil pills make a child a genius?

Fish-oil case study The “Durham trials” was published by the British media A trial of fish-oil capsules was intended to be given out to 5000 children Impressive results had been confidently predicted

Methodology Recruit 5000 children in their GCSE year Give them 6 fish-oil capsules a day Compare their results Children who are given fish-oil capsules What the council would have estimated for children without the capsule Methodology

Importance of a placebo group “Whatever you do to children, in a trial of a pill to improve their performance, their performance will improve” Children’s skills improve over time Placebo effect Hawthorne effect – alteration of behavior by the subject of a study due to their awareness of being observed.

Fish-oil case study Durham has a bad exam record Current A-level syllabus are easier than old O-level papers Present day university papers are easier than old A-level papers

Outcome News reported many positive fish oil trials being performed on the children Researcher who regularly appeared on TV, often used technical terms such as ‘limbic’ There were plenty of complicated graphics but no statistics. There were no scientific literature or published studies about the positive effects of fish oil pills in children.

Medicalization A process by which problems and issues become defined and treated as a medical problem. Medicalization Treatment

Fish-oil case study GCSE results showed a decreasing rate of improvement Durham council announced that there had never been any intention of measuring exam performance

Implications Undermine the public’s understanding of the nature of evidence and research Ethical issues Educationalists, academic researchers, parents and the public should be permitted to review the methods and results and draw their own conclusion

Conclusion Importance of a placebo group- researcher is able to better evaluate the true overall effect of the treatment under study. Generating news coverage as a means of increasing brand awareness of a product is very common We should exercise discretion with information presented to us by the media and make our own judgements.

Thank you!
