What serves as a preview and summary of an article, helping readers decide if they want to read the full piece?

The abstract serves an essential function in scholarly articles by summarizing the primary objectives, methodology, results, and conclusions of the study in a concise manner. This brief overview allows readers to quickly assess the relevance of the full article to their interests or research needs.

Typically, an abstract is structured to provide enough information that highlights the significance and findings of the research without overwhelming details, facilitating informed decision-making about whether to engage with the complete work. In many academic and professional circles, abstracts are often required for presentation at conferences or publication in journals.

In contrast, an introduction sets the stage for the article, outlining objectives and background but does not provide a succinct summary. Conclusions summarize the results and implications after the content has been presented, and an executive summary, while similar to an abstract, is more often used in reports and business documents to provide a comprehensive summary of a larger document rather than a research article specifically.
