Final answer:
An ineffective introduction fails to clearly define the thesis, lacks development in its paragraphs, and does not adequately integrate evidence, often resulting in confusion for the reader. It also shows little consideration for audience engagement and the cultural context of the subject.
Step-by-step explanation:
An ineffective introduction in writing can greatly impact the reader's understanding and interest in an essay or piece of writing. Characteristics of an ineffective introduction include a lack of a clear thesis, insubstantial problem-and-solution paragraphs without a central point, recommendations that are inappropriate or absent, and poor integration of evidence. Moreover, the language used may be confusing or inappropriate, which can disengage the reader. This leads to the reader being not drawn into the essay, thereby keeping them from being interested or having to think about the topic. The writer often shows little or no concern for the audience's prior knowledge and beliefs about the topic and ignores multiple perspectives. Additionally, the effectiveness of the introduction is further diminished when there is little understanding of the cultural context and genre of the subject.
