Brock in 1965 found that source-recipient similarity can increase influence and persuasion. He found that a in a large retail store, in the paint department, a paint salesman was more influential when he had performed a similar job to the target (buyer) than when the salesman’s previous job was unrelated yet he was highly experienced. He also found that the if the worker in the dept store had a similar preference of magnitude of paint to the customer, the customer was more likely to buy that paint than if the worker had a different or no preference.
