Penelitian ini menjawab pertanyaan yaitu faktor apa di antara variabel persepsi terhadap keadilan sosial atau variabel kepercayaan interpersonal yang paling memprediksi kepercayaan politik. Metode penelitian yang dipakai adalah korelasional, dengan subjek penelitian yaitu mahasiswa perguruan tinggi se-Indonesia yang berusia di atas 19 tahun, dengan teknik accidental sampling, dan didapatkan sejumlah 1161 responden. Persepsi keadilan sosial diukur dengan Procedural dan Distributive Justice Scale (Blader & Tyler, 2003), kepercayaan interpersonal diukur dengan Propensity to Trust Scale (Evans & Revelle, 2008), dan kepercayaan politik diukur dengan Citizen Trust in Government Organizations Scale (Grimmelikhuijsen & Knies, 2015). Hasil menunjukan bahwa kepercayaan politik berkorelasi positif secara signifikan dengan persepsi keadilan sosial (r = 0.714, n = 1161, p>0.01, one-tailed) dan kepercayaan interpersonal (r = 0.112, n = 1161, p>0.01, one-tailed). Hasil dari analisis regresi juga menunjukan bahwa persepsi keadilan sosial menjadi prediktor yang lebih kuat (β = 0.711) dibandingkan kepercayaan interpersonal (β = 0.114) terhadap kepercayaan politik.

Results show that political trust was positively correlated with perceived social justice (r = 0.714, n = 1161, p>0.01, one-tailed) and interpersonal trust (r = 0.112, n = 1161, p>0.01, one-tailed). Regression analysis showed that perceived social justice was the better predictor (β = 0.711) rather than interpersonal trust (β = 0.114) towards political trust.
