Stochastic dynamical reduction for the case of spin-z measurement of a spin-1/2 particle describes a random walk on the spin-z axis. The measurement’s result depends on which of the two points: spin-z=±ħ/2 is reached first. Born’s rule is recovered as long as the expected step size in spin-z is independent of proximity to endpoints. Here, we address the questions raised by this description: (1) When is collapse triggered, and what triggers it? (2) Why is the expected step size in spin-z (as opposed to polar angle) independent of proximity to endpoints? (3) Why does spin “lock” in the vertical directions? The difficulties associated with (1) are rooted, as is Bell’s theorem, in the time-asymmetric assumption that the present distribution over hidden variables is independent of future settings. We believe, a priori of any of the experiments of modern physics, that such a time-asymmetric assumption is dubious when probing the microscopic scale. As for (2) and (3), they are simultaneously resolved by abandoning the fundamental distinction drawn between spin and spatial angular momentum, and by appealing to very tiny (in both magnitude and spatial extent) but numerous patches of magnetic noise in the Stern-Gerlach’s field

We group encephalitic behaviors as shown in Table 1. It is striking that the majority of these behaviors, namely groups 1 and 2, help spread viral and bacterial infections underlying encephalitis, a situation similar to Ophiocordyceps unilateralis .Could some of the behaviors in Table 1 be of utility to the host as well? Note that the behavioral symptoms may not coincide with impaired intellect . Furthermore, these symptoms may be vestigial in the sense of having been of utility to the host species at a time when the latter possessed lower intelligence to begin with. It is also important to note that encephalitis is often triggered by physical and emotional stress, so that utility of behaviors is better assessed for such conditions.Continuous and compulsive exploration of one’s environment is of course a recipe for learning and discovery.
