The graph shows average partisanship of a phrase on the Y-axis from 0.5000 to 0.5100 and year on the X-axis from about 1905 to 2020. Two lines are shown. A solid line labelled Real fluctuates between about 0.5010 and 0.5055, with frequent short term peaks and troughs across the full period. A dashed line labelled Random remains close to 0.5000 with small variations throughout. Shaded areas around both lines indicate variability over time.Left-right partisanship after Soviet Union related speeches have been dropped, controls for government status, speaker gender and region
Note(s): Results are based on regressions with controls for government status of speaker’s party, speaker’s gender and the region of the speaker. Confidence intervals are based on subsampling and have 80% nominal coverage. The confidence intervals are computed via subsampling. The series breaks in 1915–1916, when the parliament did not gather, and in 1918 and 1939, when the number of speakers from left parties was below 30 (1 and 24, respectively). Speeches mentioning Soviet (“neuvosto”), words related to the Finno-Soviet Co-operation pact (“yya”, “ystävyys”, “yhteistyö”, “avunanto”) and the words socialist (“sosialisti”) and communist (“kommunisti”) have been dropped in this analysis
