Abstract

Populism is a concept employed to qualify the political behavior of a large number of actors at a worldwide scale, with scientists classifying the latter into populists and non-populists according to dimensions such as ideology, strategy, discourse, economic policy, and even style. This article analyzes existing schools of thought on the nature of populism and argues that conceptualizing populism as a specific type of anti-elite discourse in the name of the People is both conceptually and methodologically the most coherent and useful way to understand the phenomenon. Additionally, it suggests discarding crude, dichotomous classification in favor of a gradated view of populist mobilization by means of quantifying populist discourse and observing its spatial and temporal variation. It adds value to current methods of measurement by demonstrating why and how clause-based semantic text analysis can provide optimal quantitative results while retaining qualitative elements for mixed-methods analysis. Aiming, moreover, at expanding the scope of populism studies by overcoming a narrow view that focuses exclusively at party system developments, it applies semantic text analysis to the study of grassroots mobilization during the Great Recession. Results point to the wide use of populist discourse on the part of movement activists seeking an inclusive language when framing disparate social grievances in a given constituency, a finding with important implications with regards to how populism can facilitate straddling the divide that purportedly distinguishes institutionalized party system behavior from the social movement milieu.

Notes

  1. The list is non-exhaustive.

  2. Müller (2016), for instance, argues that the US People’s Party in the 1890s was not populist.

  3. For example, Mair (2002) discusses Tony Blair as a populist leader in the UK.

  4. For an overview of the academic development of the term, see Moffitt (2016), Chap. 2.

  5. Harrison and Bruter (2011) worked along similar lines in their analysis of the European extreme right.

  6. Pauwels (2011) includes absurd, admit, politic*, propaganda, ruling*, tradition*, and truth; (Harrison and Bruter 2011) include nonsense, shambles, chaos, contempt, favouritism, blind, innovation, and regret; Oliver and Rahn (2016) include politician(s), IRS, donors, and CEOs. The validity of such spurious choices is evidently contested.

  7. The numbers reflect both single words and n-grams employed by the authors. Words can be stemmed or remain whole. Oliver and Rahn (2016) only provide examples from their dictionaries rather than their whole content.

  8. Rooduijn and Pauwels (2011) had to include ‘context-specific words’ in their cross-national study, since many idiosyncratic political expressions fail to transcend linguistic barriers. The significance of the word regenten for Flemish and Dutch populism, or katestimeno for Greek populism are telling illustrations. In terms of proportion, the Dutch dictionary in Rooduijn and Pauwels (2011) contains fourteen ‘core’ words and seven ‘context-specific’ words, proving that contextual impact is far from negligible when analyzing text (Krippendorff 2004).

  9. Bonikowski and Gidron (2016) read 40.1% of their total dataset, hand-coding excerpts from 890 speeches, and manually assessing all positive instances identified in a first iteration of dictionary analysis. They report a Cohen’s kappa of 0.70 for intercoder reliability when performing manual coding (footnotes 5–6).

  10. A higher range would require splitting text into syllables or letters (nonsensical in this context).

  11. Their rationale is using this evaluation as a boolean variable for statistical analysis.

  12. Bernhard et al.’s (2015) coding scheme draws from March (2012) with the overall score for each sample unit resulting from the combination of scores in three different dimension.

  13. Hawkins (2009) attributes this moderate performance on the large number of coders, the small set of speeches, and the limited experience of coders in reading political texts.

  14. For a critique against using Cohen’s kappa for content analysis and a way to calculate the reliability of ordinal data, see Hayes and Krippendorff (2007).

  15. Personal communication with authors.

  16. The ‘people index’ incorporates references to any ‘group[s] of people having explicit constant features in common’ (Reungoat 2010: 311).

  17. Reliability cannot be assessed since coding was performed exclusively by the first author (personal communication with first author).

  18. The method is also applied to newspaper articles in Rooduijn (2014), with improved reliability scores. In the same paper, scores given to ‘introductory paragraphs’ are doubled and paragraphs in long manifestos are weighted differently than those in shorter ones, thus employing an interesting non-linear scoring scheme.

  19. Apart from the option of manually distilling semantic triplets, software packages exist (e.g. IDEA, KEDS) to parse text for syntactical elements. With improved tools, we can expect increased reliability and even lower processing costs in the future. See discussion in Franzosi (2010: 62–63).

  20. To compensate for any potential loss in contextualization, coders in CBSTA projects are instructed to draw judgment from larger context units (Krippendorff 2004), or even the entire sample unit, prior to appending codes to individual semantic triplets.

  21. The dataset was coded by two individuals (one of which one was the first author) with no actual overlap in content, and therefore, no reliability test was performed (personal communication with first author).

  22. The J14 movement in Israel did not produce a manifesto and therefore is not part of the case selection.

  23. Preparation of each manifesto took an average of 2 h.

  24. The researcher was not part of the coding team.

  25. The software package was used to streamline the coding process and avoid typing or other unnecessary coding mistakes. Any spreadsheet or word processing application can be used with equal merit.

  26. The use of decision schemes is another significant advantage of this method, enhancing reliability by organizing the coding process along a series of dichotomous decisions, increasing coding speed and minimizing errors owed to coder fatigue (Krippendorff 2004).

  27. The moderate intercoder agreement in identifying the presence of an actor in the clause (NAC) is largely due to disagreement over the eligibility of vague notions such as ‘society’ or ‘humanity’. Further training can disambiguate such observations and lead to highly increased intercoder scores altogether.

  28. The value of factor c, indicating weight, is of course a matter of perspective.

  29. Residual categories receive no score.

  30. The unusually rounded score for the manifesto of the benchmark case was a matter of coincidence.

  31. For instance, a text with 10% full populist frames, 15% people-centrism, and 15% anti-elitism yields PDI = 0.20. A text with no full populist frames would require a combined 60% of partial populist frames to pass this threshold, a rather unlikely scenario for non-populist discourse. Hence, the possibility of a false positive is very slim.
