  1. 1. A lecture by Melih Arat – melarat.blogspot.comBorn Entrepreneurs, Born LeadersHow Your Genes Affect Your Work Life Scott Shane
  2. 2. A lecture by Melih Arat – melarat.blogspot.com The Nature Nurture Debate• Make two columns on a sheet of paper –• 1) nature; 2) nurture• Write characteristics you believe are mostly nature or mostly nurture in the appropriate column• If the characteristic was nurture, what seemed to be the influences?
  3. 3. A lecture by Melih Arat – melarat.blogspot.com Genetic Technologies….• An Australian company called Genetic Technologies offers a test to identify the version of the ACTN3 gene people have. With a simple swab of the mouth, a person can gather some DNA and ship it to the company’s lab.• Within four weeks, the company will send back a report that identifies which sports the person is best suited for.
  4. 4. A lecture by Melih Arat – melarat.blogspot.com The Nature/Nurture Debate• How great is the influence of genes or environment on our behavior, personality, biology, etc.?
  5. 5. A lecture by Melih Arat – melarat.blogspot.com The Simple View• Behavior = genes + environmentThe Realistic View• Behavior = genes + prenatal environment + parental influence + nutrition + family income + education + culture + traumas + chance …
  6. 6. A lecture by Melih Arat – melarat.blogspot.comGenetics and Behavior Nucleus Chromosome Gene Cell DNA
  7. 7. A lecture by Melih Arat – melarat.blogspot.com Genes: Essential Definitions• Chromosomes – threadlike structures made of DNA that contain the genes• DNA (deoxyribonucleic acid) – complex molecule containing the genetic information that makes up the chromosomes – has two strands-forming a “double helix”- held together by bonds between pairs of nucleotides
  8. 8. A lecture by Melih Arat – melarat.blogspot.com Behavior GeneticsIdentical twins Fraternal twins • Identical Twins – develop from a single zygote (fertilized egg) that splits in two, creating two genetic replicas • Fraternal Twins – develop from separate zygotes – genetically no closer than brothers and sisters, but they share the fetal environment Same Same orsex only opposite sex
  9. 9. A lecture by Melih Arat – melarat.blogspot.com Nature v Nurture: Twin Studies Oskar Stohr: raised by catholic Jack Yufe: grandmother in raised by Nazi Germany Jewish father in CaribbeanIf we had identical twins reared apart could we separate the effects ofphenotype, of genotype, and of the environment. In some cases this hashappened.

  12. 12. A lecture by Melih Arat – melarat.blogspot.com Separated Twins• Born in 1940, Jim Springer and Jim Lewis were adopted by different families. In 1979, psychologist Thomas Bouchard, interested in the nature/nurture debate, began a detailed investigation of identical twins who were separated at birth. The Jim twins caused a public stir early in this study, as they shared remarkably similar lives. Aside from the fact that they were both named Jim by their adoptive parents, the twins had both married twice - the first time to women named Linda and the second to women called Betty. Jim Springer named his son James Allen whilst Jim Lewis called his son James Alan. They both had dogs named Toy, both spent time as sheriffs deputies, they drank the same beer, smoked the same cigarettes and drove the same model of car. Tempting as it may be to view the twins case as evidence of something spooky, many of these similarities are not unlikely. Jim is a very common name, and so was the model of car they both drove.
  13. 13. A lecture by Melih Arat – melarat.blogspot.com Environmental Influences• Prenatal environment
  14. 14. A lecture by Melih Arat – melarat.blogspot.com Behavior Genetics• Adoption studies – Are adopted kids more like their biological relatives or their adopted relatives? – General findings: adoptees more like biological parents than adopted parents in intelligence and personality/temperament
  15. 15. A lecture by Melih Arat – melarat.blogspot.comNumerous studies have More than half of the shown that genes account variance between people for a big portion of the in scores on both IQ difference between assessments and tests of people in both the OCEAN model of intelligence and personality are genetic. personality. (The OCEAN model • openness to experience, • conscientiousness, • extraversion, • agreeableness, and • neuroticism, which.)
  16. 16. A lecture by Melih Arat – melarat.blogspot.com Genes• Genes are the basic unit of heredity.• They are composed of deoxyribonucleicacid (DNA), which carries instructions for how to make molecules called proteins.7
  17. 17. A lecture by Melih Arat – melarat.blogspot.com• Very simply, my thesis • Genes don’t cause people• is that it is very unlikely that to engage in any behaviors what people do in orhold any attitudes.13 organizations is solely the • They merely influence the• result of environmental odds that someone will forces. Genetic factors engage in those behaviors influence the tendency of or hold those attitudes.• people to engage in workplace behaviors in a myriad of ways, and these• effects have implications that you should be aware of.
  18. 18. A lecture by Melih Arat – melarat.blogspot.comgenetic and environmental factors both matter.• Consider height, for example. Some of us have variants of genes that make us shorter, while others have versions that make us taller. But• the height genes’ effects don’t negate environmental influences on how tall we are.
  19. 19. A lecture by Melih Arat – melarat.blogspot.com Work is influenced by genes.• Scientists recognize that what you do at work is influenced by your genes.• In fact, studies show that over one-third of the differencebetween people on virtually every employment- related dimension investigated, including work interests, work values, job satisfaction, job choice, leadership turnover, job performance, and income, is genetic.
  20. 20. A lecture by Melih Arat – melarat.blogspot.comYou can always overcome your genetic predispositions• The knowledge of how genetics influences your behavior is also useful for acting in ways contrary to your ‘‘nature.’’• How you behave at work is not genetically predetermined; your genes just make you more likely to conduct yourself in certain ways and not others.
  21. 21. A lecture by Melih Arat – melarat.blogspot.com Emotional Response DNA-CREB1• Bosses get angry at subordinates, subordinates get angry at bosses, customers get angry at suppliers, suppliers get angry at customers, and team members get angry at each other.• some people are better than others at dealing with this distemper.
  22. 22. A lecture by Melih Arat – melarat.blogspot.com DNA interaction with External Forces• Becoming antisocial depends on the combination of the version of the gene and emotional or physical maltreatment.
  23. 23. A lecture by Melih Arat – melarat.blogspot.com Gene-Environment Correlation• Researchers have recently found that children with a particular version of the dopamine receptor gene DRD2, (which I will call the ‘‘impulsiveness’’ gene) are less likely to go to college than other kids.• This more negative behavior leads their parents to become less involved in their education.
  24. 24. A lecture by Melih Arat – melarat.blogspot.com Genes and becoming a CFO• Suppose you were born with versions of certain genes that made you better than other kids at math. Your genetic gift led you to gravitate toward mathematics in school because you liked all of the positive feedback that your parents and teachers provided when you did a good job.• Your quantitative skills made you a good student, which increased the odds that you would choose to go to college. At college you majored in finance, which you found very easy, given your innate mathematical aptitude. Of course, going to college and majoring in math was key to being able to get a job in the finance department of a Fortune 500 company.
  25. 25. A lecture by Melih Arat – melarat.blogspot.com The ‘‘novelty-seeking’’ gene (DRD4)• The ‘‘novelty-seeking’’ gene (DRD4) gene interacts with the ‘‘worrier’’ gene (COMT) to affect novelty seeking.• People who have certain versions of each gene are much more likely than other people to seek out new situations and experiences, even if doing so involves taking some risks.
  26. 26. A lecture by Melih Arat – melarat.blogspot.com• Your DNA influences the probability that you will behave in a particular way; it does not assure it.
  27. 27. A lecture by Melih Arat – melarat.blogspot.comThe Effect of Genes on Work Interests• Are you a sports nut, an artsmaven, amusic fanatic, or a collector of ancient Roman coins? Whatever your interests, some part of your preference can be traced to your DNA. Take your intellectual pastimes, for example. Do you prefer to read books or listen to music? One study found that about 21 percent of the difference between people in the kinds of intellectual activities they prefer can be accounted for by their genes.
  28. 28. A lecture by Melih Arat – melarat.blogspot.com Genetic Based Ocean Model Personality and Career Choices• People who are imaginative, creative, and inventive—characteristics that psychologists combine in a trait called openness to experience— tend to prefer artistic, investigative occupations, such as acting and research.• Extraverted people tend to prefer enterprising and social jobs,such as business and nursing.• Agreeable people tend to prefer social jobs, such as child care and sales.
  29. 29. A lecture by Melih Arat – melarat.blogspot.com Genetic Influence on Character and Behaviour• Harm avodiance low – sales• Harm avoidance high- accounting• Self-confidence %32 genetic• Stress Reaction %44 genetic• Cognitive, number and verbal skills %50 genetic
  30. 30. A lecture by Melih Arat – melarat.blogspot.com Genetic predispositions • numeracy might have higher odds of becoming an accountant,since accountants spend their days analyzing numbers. • verbal understanding (the ability to comprehend written andspoken words) might be more likely to become a book editor,since editors need to read and understand authors’ books. high perceptual speed (the ability to see similarities in betweendisparate things quickly) might have greater chances of becominga pilot, since pilots need to react quickly to changing circumstances. • deductive reasoning might have higher odds of becoming a marketresearcher, since market researchers use deductive analysis toidentify attributes to put into products. • spatial visualization might be more likely to become an interiordesigner, since interior designers need to envision the design ofrooms.
  31. 31. A lecture by Melih Arat – melarat.blogspot.com Values and Genes• Even to be a religious person is caused by genes.• Majority of the variance between people comes from genetic factors. Even the most rigorous studies of twins reared in different homes show that more than half of the difference in levels of ‘‘social conservatism’’ is genetic
  32. 32. A lecture by Melih Arat – melarat.blogspot.com Personality• Psychologists and humanresource experts have found that people with high core self- evaluation (those with high self esteem, self- efficacy, and emotional stability, and an internal locus of control) tend to be satisfied with whatever job they have.
  33. 33. A lecture by Melih Arat – melarat.blogspot.com How do you make your decisions?Do you think quickly, but make decisions calmly?That might be because of the combination of serotonin and thehumanbrain- derived neurotropic genes (BDNF) that you have. (Iwill call BDNF the ‘‘memory’’ gene.) What about being a risktaker?That might come from your versions of the ‘‘worrier’’ (COMT)and ‘‘impulsiveness’’ (DRD2) genes.
  34. 34. A lecture by Melih Arat – melarat.blogspot.com Risk Taking?You won a lottery and have to choose between acertain payment of$2,000, a 50–50 chance of getting either a $5,000payment or nothing,and a 20 percent chance of a $15,000 paymentand an 80 percentchance of receiving nothing. Which do you select?
  35. 35. A lecture by Melih Arat – melarat.blogspot.comManagement Styles and GenesDifferences in DNA influence whether peopleare aggressive or laid-back negotiators, planning-focused orlaissez-faire organizers, frugal or expansive spenders, among ahost of other dimensions that make up a person’s supervisorystyle.In fact, the data show that our genes even affect ourmanagement potential, with about half ofthe difference between people on tests of managementcapability being accounted for by genetic factors.Born Control Freaks, Innate Planners, Rule Breakers,Persistents, born competitors
  36. 36. A lecture by Melih Arat – melarat.blogspot.com Attitudes Toward LeadershipDo you have a positive or a negative view toward directingothers? Do you aspire to be a leader, or is it something that youdon’t care for, or even dislike? However you answer thesequestions, your genes are partially responsible.Some portion of your attitude toward leadership is genetic.
  37. 37. A lecture by Melih Arat – melarat.blogspot.com Born Smart and CreativeOur genes also influence our creativity through another path, one thatbegins with effects on the enzymes that produce neurotransmitters. Ourgenes, we know, influence the development of a number of key brainchemicals, including dopamine, serotonin, and monoamine oxidase,which affect how our brains function. People with certain versions ofseveral neurotransmitter genes produce more serotonin and dopaminetransporters and receptors and less of the chemicals that decomposethem.
