Social Psychology experiments are most useful when they maintain objectivity. This is because objectivity allows the experiment to be free from personal bias and subjective interpretations, ensuring that the results are based on observable phenomena and can be replicated by other researchers.

Here are the steps to answer this question:

1. Understand the question: The question is asking which of the given options is most useful in maintaining the effectiveness of social psychology experiments.

2. Analyze the options:

   • Bias: This is a preconceived notion or prejudice, which can affect the objectivity of the experiment. So, this is not a desirable quality.
   • Individualisation: While it's important to consider individual differences in psychological studies, overemphasis on individualisation can lead to neglecting common patterns of behavior. So, this alone is not the most useful aspect.
   • Subjectivity: This refers to personal perspectives, feelings, or opinions entering the research study. In scientific research, subjectivity is generally avoided to maintain the validity and reliability of the results.
   • Objectivity: This refers to the ability to observe and measure phenomena without letting personal biases or beliefs influence the observations or outcomes. In scientific research, including social psychology, objectivity is crucial to ensure that the findings are valid and reliable.
   • All of the above: This option is incorrect because, as explained, not all of the above options are desirable in social psychology experiments.

3. Choose the correct option: Based on the analysis, it's clear that 'Objectivity' is the most useful when conducting social psychology experiments.
