    "body_text": "The Neural Thickets hypothesis attributes gains from random weight perturbations to dense neighborhoods of task-specialized models. A reproduction finds a simpler explanation: perturbing one decoder block recovers much of the gain, while adding random bias only to output logits matches or exceeds full-weight perturbations on most tested reasoning tasks. The authors formalize Perturb-Select-Vote, selecting strong perturbed predictors on a small validation set and aggregating them. Vision tests under domain shift also found little extra benefit from changing all the weights. The result challenges one geometric interpretation; it does not show that every perturbation ensemble reduces to logit voting.",
