In a simple random sample, every individual in the population has an equal chance of being selected, which minimizes bias. However, bias can still occur if the sample size is too small or if the sampling method is not truly random due to practical constraints, such as non-response or selection errors. External factors, like the timing of data collection, can also introduce bias. Thus, while simple random sampling aims to reduce bias, it is not entirely immune to it.

Bias and its ramifications
Non-probability sampling methods, such as convenience sampling and judgmental sampling, are most at risk for sample bias. These approaches rely on the researcher's choice or easy access to participants, which can lead to a sample that is not representative of the broader population. As a result, findings from such samples may not be generalizable and can skew results. Probability sampling methods, by contrast, reduce the risk of bias by ensuring every individual has a known chance of being selected.
The thing that can be done to reduce bias is sampling random things
the strategy that will not help reduce selection bias is:
You can't - the best you can do is reduce it.
An individual can educate themselves on different cultures and perspectives, challenge their own assumptions and stereotypes, engage in conversations with diverse groups of people, and actively participate in promoting diversity and inclusion in their community.
bias
A blind study can help reduce bias by preventing the participants or researchers from being influenced by their knowledge of which group they belong to. This can help ensure that the results are more objective and not influenced by preconceived notions or expectations.
To reduce bias in a scientific investigation, a scientist can use randomization in sampling, blind studies, and double-blind studies. Randomization helps to minimize selection bias, while blind studies prevent participants from knowing which group they are in, reducing response bias. In double-blind studies, both the participants and the researchers are unaware of who is receiving the treatment, further minimizing bias.
Scientists who understand how science works will always be on guard against their own possible bias. And of course, there is always peer review. Scientists who do exhibit bias will eventually be challenged by other scientists.
i can only think of an example. "Why is America's govt. the best govt. in the world?" The bias is already there.
Our own points of view/ ways influence our interpretations of behaviours and experiences.

befrore there wasnt much bias now there is
