Would You Be Happier If You Were Richer? A Focusing Illusion

Science, 2006 · paper · Psychology

Reviews evidence on whether higher income brings greater happiness, arguing that people exaggerate the effect of any single factor, a "focusing illusion." Income appears to affect moment-to-moment experienced mood even less than it affects global life-satisfaction judgments.

Substance 'The correlation between the answers to these questions was -.012 (not statistically different from 0) ... but the correlation rose to 0.66': the first value has three decimals and no leading zero and is probably -.12, the value in the cited Strack, Martin & Schwarz (1988).

Only the authors can say what is right here.

Judge's note: Rests on outside knowledge: that Strack, Martin & Schwarz (1988) report r = -.12 for the general-then-specific order; the cited paper is not among the files. On the page image the value is printed '-.012', the only three-decimal correlation in the paper and without the leading zero that its partner '0.66' in the same sentence carries; all other correlations (0.32, 0.20, 0.06, 0.01, .14, .18) have two decimals. The format oddity is visible in the PDF; the correct value can only be confirmed by the authors or the source. The qualitative statement (not different from 0) holds either way.

Judge's note: Read all 31 entries on the page 13 and 14 images and searched the text for "Stutzer". The only match in the list is reference 12, B. Frey & A. Stutzer, Happiness and economics (2002), which is a different work, year and author order. The work cited for the commuting claim on page 8 (callout 28) therefore cannot be identified from the paper. Only the authors can supply the missing reference. The author-year form for Kahneman et al (2004), which is reference 14, is a minor style inconsistency within the same note.

Judge's note: Rests on outside knowledge: that the Texas sample of working women was used in Kahneman, Krueger, Schkade, Schwarz & Stone (Science 2004), i.e. reference 14; the paper itself does not say which study used that sample. From the files: reference 29 is a book by Kahneman, Diener & Schwarz (cited as editors of the same volume in references 8, 26 and 27), reference 29 is cited nowhere else, and reference 14 is the one the text cites for the Day Reconstruction Method. An edited handbook is an unlikely source for a survey sample, so the pointer probably should be (14); the authors must confirm.

Judge's note: Read Table 1 on the page image: the income row has one asterisk, the other three rows (13.2**, 42.1**, 30.5**) have two, and the footnotes define only '**'. No definition of '*' appears anywhere in the table or text. Either a footnote line is missing or the cell should read '**'; only the authors can say.

Judge's note: Rests on outside knowledge: that Kahneman, Krueger, Schkade, Schwarz and Stone, 'A survey method for characterizing daily life experience: the Day Reconstruction Method', is Science 306, 1776-1780 (2004). The page 13 image reads "306, 1176 (2004)", so the printed text is as quoted. The true first page cannot be checked from the files provided; if it is 1776, this is a one-digit slip.

Wording Text describes the good-mood measure as 'respondents’ own global estimate of the percent of time they spent in a good or bad mood in the previous day' (and note 15: 'the retrospective report of mood on the previous day'), but the Table 3 note defines it from questions with no reference to yesterday: 'When you are at home, what percentage of the time are you in a bad mood...'

Only the authors can say what is right here.

Judge's note: Read page 5, note 15 on page 13 and the Table 3 note on page 11. The Table 3 note quotes present-tense questions about mood in general at home and at work, averaged; the 'yesterday' wording appears only in the Table 1 footnote, which is the Texas sample. The column head 'Percent of Day in Good Mood' does not settle it. The two descriptions of the same variable (r = 0.20 with income) differ; which is right only the authors can say.

Wording Text says the predictions are those 'offered by the entire group (including individuals whose reports were included in the actual mood column)', but Table 1 footnote 2 gives only 83-87 respondents per predicted cell (e.g. 'Actual (n=82, 221), Predicted (n=85, 87)'), fewer than the actual-report groups for the same variable.

  • p. 9 Table 1, footnote 2

Only the authors can say what is right here.

Judge's note: Read page 3 and Table 1 footnote 2 on page 9. Predicted n is 83, 83; 85, 87; 84, 84; 83, 85, while the two actual groups for one variable sum to 303, 312 and 307 (and those are restricted to respondents whose preceding day was a workday). The predicted n also differs between the two groups of a pair (85 vs 87, 83 vs 85), so each prediction item was evidently answered by a subsample. The paper does not describe that design anywhere; 'entire group' may mean 'not restricted to people in that circumstance', so this is a wording ambiguity for the authors.

Judge's note: Read page 5, the Table 3 note and the Table 4 note. Searched the whole text for an exclusion or complete-data rule: none is given. 745 is plausibly the subset with the variables needed for Table 3 (e.g. income) and 810 the full survey, but the text says the data were 'collected from 745 women'. Only the authors can say which figure describes what.

Wording EMA paragraph reports 'The correlation between personal income and the average happiness rating during the day was just 0.01 (p=0.84), while family income was significantly positively correlated with ratings of Anger/Hostile', then concludes about 'higher income' without distinguishing the two income measures.

Only the authors can say what is right here.

Judge's note: Read page 6. The happiness correlation is given for personal income and the anger, anxiety and excitement correlations for family income; the summary sentence treats them as one measure and nothing in the text or notes 17-18 explains the switch. Could be a deliberate choice or a slip in one label.

Wording 'People with greater income tend to devote relatively more of their time to work, compulsory non-work activities (such as shopping and childcare) and active leisure': for women in Table 4 the Compulsory share does not rise with income (35.6%, 34.3%, 35.9%).

The claim holds for work, active leisure and passive leisure in both sexes, and for compulsory activities only for men. 'Tend to' is hedged, so this is a mild overstatement.

Typo The happiness question is quoted two ways: page 2 has “Taken all together, would you say that you are very happy, pretty happy, or not too happy?” while the Table 2 stub has "Taken all together, how would you say things are these days--would you say that you are very happy, pretty happy, or not too happy?"

    "Taken all together, how would you say things are these days--would you say that you are very

Judge's note: Read both pages. Both are set in quotation marks as the question asked; the introduction omits 'how would you say things are these days--' with no ellipsis. The introduction is probably a deliberate shortening, so this is a minor consistency point.
