An autonomously-powered counting device which can be used to collect, store and count several arrays on a single apparatus and perform a statistical comparative analysis under optimum neutrality conditions, includes a case which can permanently collect opinions without any human intervention with buttons connected to an array-counting and storage circuit. A time delay system is used to prevent votes from being repeated in rapid succession. The arrays are restored by consulting one or more counters or by remotely transmitting arrays via Hertzian waves, an optical link or a cable. The case ( 1 ) includes an integrated zone used to display the question posed to the polled users. The question posed may vary by command, by pre-defined programming, in a random manner, according to exogenous parameters or as a function of the response given to the previous question posed.
