Scientists have to put away any bias they may have, when doing experiments.
Oh, dude, scientists do experiments more than once because they want to make sure their results aren't just a fluke. Like, imagine if they discovered a cure for something, but it only worked once out of a hundred tries - that would be a bummer. So, they repeat experiments to make sure their findings are legit and not just a one-time lucky shot.
The concept of human development was introduced by psychologist Erik Erikson in his theory of psychosocial development. He proposed that individuals go through a series of stages throughout their lives, each characterized by specific challenges and tasks that contribute to their overall growth and development.
Examples of uncontrolled or informal observation in psychological research include naturalistic observation, where researchers simply observe subjects in their natural environment without any manipulation or control, and case studies, where researchers closely observe and document the behavior of an individual or small group without imposing any external conditions. These methods lack the systematic control and manipulation of variables found in controlled experiments, making the results less reliable and more prone to bias.
The primary difference is that in an experiment, the researcher actively manipulates or controls one or more variables to observe the effect on another variable, while in an observational study, the researcher simply observes and records data without intervening or controlling any variables. Experiments allow for more control over variables and can establish cause-and-effect relationships, while observational studies can only establish correlations.

Leif Erikson, aka Leifur Eiríksson, was not sponsored by any countries. His father, Erik Thorvaldson, aka Eiríkr Þorvaldsson, aka Erik the Red, was banished from Iceland after "some killings", and sailed to Greenland accordingly. Eriksson first stumbled into North America when his ship was blown off course when he was returning to Greenland from Norway. He spotted land lush with natural resources such as timber, wild grain, and grapes. He later mounted an expedition to return the land he had spotted - in search of more and better land for his family and others who had moved to Greenland.
