This claim is untrue. By sending out surveys and doing in-person interviews, marketing researchers are unable to independently search secondary data sources.
Secondary data is information obtained from publicly available sources such as websites, newspapers, or other publications. Prior to using secondary data from a source, it is essential to verify the source's reliability. A frequent example of a secondary data source is internal business data from a company, such as sales and marketing records, customer account information, and statistics on product consumption and purchase.
