There are several major types of experiments used across scientific disciplines, each suited to different research goals and environments. Here’s a breakdown of the most commonly recognized types:
🔬 Main Types of Experiments
Type of Experiment Description
Controlled Experiment Compares two groups that differ only in one variable to determine cause-effect.
Natural Experiment Occurs in a real-world setting without manipulation by the researcher.
Field Experiment Conducted in a natural environment with some control over variables.
Laboratory Experiment Takes place in a controlled setting where variables can be precisely manipulated.
Quasi-Experiment Similar to controlled experiments but lacks random assignment to groups.
Each type has its own strengths:
Lab experiments offer high control and internal validity.
Field experiments provide more realistic insights but less control.
Natural and quasi-experiments are useful when manipulation isn’t possible or ethical.

Self-defeating behaviours are thoughts, habits, or actions that work against a person’s own goals, wellbeing, relationships, or success, even when the person consciously wants a positive outcome.
Common examples
Self-defeating behaviour What the person wants How it defeats the goal
1. Procrastination: To succeed-Delays necessary action
2. Self-sabotage: To achieve a goal-Creates obstacles or gives up prematurely
3. Excessive perfectionism: To do things well Prevents completion or creates fear of failure
Avoiding challenges-To improve Prevents learning and growth
4. Negative self-talk: To feel confident Reinforces feelings of inadequacy
Seeking repeated reassurance-To feel secure Can increase dependence and anxiety
5. People-pleasing: To maintain relationships- -Neglects one’s own needs and may create resentment
6. Impulsive behaviour: Immediate relief/pleasure Produces longer-term problems
Repeatedly choosing harmful relationships-To have companionship Maintains an unhealthy relational pattern
7. Giving up after minor setbacks: To avoid disappointment-Prevents achievement
Psychological mechanism
A typical cycle is:
Trigger → thought/belief → emotion → behaviour → short-term relief → long-term negative consequence → reinforcement of the original belief
For example:
> “I might fail” → anxiety → avoid the task → immediate relief → task remains unfinished → “I can’t succeed” becomes stronger.
An important point is that self-defeating behaviour is usually not deliberate self-destruction. The behaviour often provides some immediate psychological benefit—such as reducing anxiety, avoiding embarrassment, obtaining reassurance, or maintaining a familiar situation—but creates a disadvantage later.
In clinical assessment
It is useful to distinguish self-defeating behaviour from self-harm. Self-defeating behaviour can be relatively ordinary and unconscious (e.g., procrastination or avoidance), whereas self-harm specifically involves intentional injury or harm to oneself.
