Hierarchical Bayesian inference of the ΔI distribution. The black curve shows the inferred distribution for the full sample, while the orange and blue curves correspond to systems hosting giant inner planets (M_in > 0.3 M_Jup or 95 M_⊕) and lower-mass inner planets (M_in < 0.3 M_Jup or 95 M_⊕), respectively. The gray dotted curve represents the isotropic expectation. The quoted ﹩{\rm{\Delta }}\mathrm{log}Z﹩ values are relative to the isotropic model.
