    {
      "part": "during-outcome-phase-responses-low",
      "whole": "insula-rois-responded-more-low",
      "why": "The raw low-outcome insula responses (Social > Partner) are one measure of the insula ROI guilt result, which subtracts the high-outcome response from this."
    },
    {
      "part": "difference-response-between-low-high",
      "whole": "insula-rois-responded-more-low",
      "why": "The low-minus-high difference being larger in Social is the 'even after subtracting high outcomes' clause of the insula ROI guilt result stated on its own."

      "part": "responsibility-model-yielded-higher-values",
      "whole": "likelihood-ratio-test-showed-responsibility",
      "why": "The R-squared comparison across models is one leg of the model-selection verdict that the Responsibility model fitted the happiness data best."

      "part": "participant-momentary-happiness-varied-rewards",
      "whole": "responsibility-redux-model-incorporating-expected",
      "why": "That happiness varied with the participant's own rewards is one component of the reward dependencies the Responsibility Redux model was fitted to capture."

      "part": "participant-momentary-happiness-varied-rewards-2",
      "whole": "responsibility-redux-model-incorporating-expected",
      "why": "That happiness varied with the partner's rewards is the other reward-source component the Responsibility Redux model captures."

      "part": "participants-chose-risky-option-lottery",
      "whole": "participants-showed-very-similar-risk",
      "why": "The frequency of risky choice across Solo and Social is one of the three measures the 'similar risk preferences' conclusion integrates."

      "part": "participants-slightly-more-risk-averse",
      "whole": "participants-showed-very-similar-risk",

      "part": "risk-premiums-not-differ-between",
      "whole": "participants-showed-very-similar-risk",
      "why": "The risk-premium comparison is the third measure feeding the 'similar risk preferences' conclusion, reconciled with the small Study 1 rho tendency."

      "part": "guilt-effect-occurred-whether-participant",
      "whole": "both-studies-participants-felt-worse",
      "why": "That the guilt effect held whether the participant's own outcome was high or low is one robustness condition of the behavioural guilt effect."

      "part": "responsibility-choices-not-influence-happiness",
      "whole": "both-studies-participants-felt-worse",
      "why": "The null for high partner outcomes states the boundary condition that the guilt effect is specific to low outcomes."
