The present disclosure relates to method and system for unbiased execution of tasks using neural response analysis of users by neural response analysis system. The neural response analysis system comprises providing one or more predefined neural stimulus, to plurality of users, receive neural responses from plurality of users in view of one or more predefined neural stimulus, correlate one or more neural responses of plurality of users with corresponding data associated with each of plurality of users stored in stimulus response mapping database to create logical matrix indicative of one or more solution parameters for resolving task, create solution model to resolve task based on logical matrix, where solution model eliminates biases and preferences of plurality of users determined based on correlation.
