Write 5-7 sentences about your own personal observations in which you have been part of a "filter". You might have experienced this is in your Twitter feed, specific advertisements, or your search engine results. Be specific.
I made a search for a product on an online grocery store. The search results came in and I bought the product. On subsequent visits to the grocery store website or on browsing other sites, I had special advertisements pop up. These advertisements were suggesting products to me similar to the one I bought on the grocery store. It was a targeted advertisement that had been sent based on my recent searches and purchases on the site. So I knew that was a filter.
