contents This paper uses approximate analytical formulas and numerical results with the bino-dominated dark matter (DM) as an example to analyze the impact of the LUX-ZEPLIN (LZ) experiment on the DM phenomenology and naturalness in the Minimal Supersymmetric Standard Model (MSSM). We conclude that the limitation of the latest LZ experiment worsens the naturalness of the MSSM, as the predictions of the $Z$-boson mass and DM relic density demonstrate, particularly in the regions where the correct DM relic density is obtained by the $Z$- or $h$-mediated resonant annihilations.
