Final answer:
There are multiple reasons why some gurus may lack the ability to deliver real results, including lack of practical experience, misleading marketing tactics, and insufficient training in their field.
Step-by-step explanation:
There can be several reasons why we see many gurus who lack the ability to deliver real results. One reason is lack of practical experience. Some gurus may only have theoretical knowledge without actually applying it in real-life situations. Another reason is misleading marketing tactics. Gurus may use persuasive advertising strategies to attract followers, even if they don't have the expertise to back up their claims. Lastly, insufficient training in their field can contribute to the lack of practical knowledge and understanding.
