Final answer:
The question discusses the use of screeners in the stock market for real-time alerts. While screeners are real-time, they may not always be 'constant' due to technological limitations. Information from streams and social media significantly influences decision-making in various aspects of life, including financial decisions.
Step-by-step explanation:
The question refers to a tool known as a screener that is commonly used in the financial market. A screener does indeed have the capability to scan the market and provide real-time alerts about new opportunities or changes in the market dynamics. However, saying it is done "constantly" might not be entirely accurate; while screeners are real-time and efficient, they work within the limitations of the technology and data feeds they use, which can sometimes result in minor delays or intervals between updates.
In the broader context of how information affects decision-making, it's evident from resources like Nielsen and McManus that streams, sponsors, and social media play a significant role in shaping our choices today. From deciding which movie to watch to which product to buy, Americans rarely make such decisions without some form of information stream, whether that be through reviews, ratings, or trends surfaced by social media.
Our choices are indeed influenced by the information provided by these sources, and similar to how an individual may curate their news consumption based on their preferences, investors and traders use screeners to filter market data according to their investment strategies and risk profiles.
