Human homing: still no evidence despite geomagnetic controls
The Journal of Experimental Biology
|January 1, 1986
Summary
Humans cannot navigate non-visually like homing pigeons, even with geomagnetic controls. Our experiments found no evidence supporting blindfolded homeward orientation in people.
Area of Science:
- Human spatial cognition
- Animal navigation
- Geomagnetism
Background:
- Baker's research suggested humans possess non-visual navigation abilities akin to homing pigeons.
- Previous replication failures were attributed to geomagnetic influences by Baker.
Purpose of the Study:
- To investigate human non-visual homeward orientation capabilities.
- To test Baker's hypothesis by controlling for geomagnetic factors.
Main Methods:
- Conducted experiments with human participants under controlled conditions.
- Introduced temporal and spatial geomagnetic controls to isolate navigational influences.
- Assessed blindfolded homeward orientation performance.
Main Results:
- No evidence of non-visual homeward orientation was found in humans.
- Results did not support Baker's claims of human navigational abilities comparable to pigeons.
- Geomagnetic controls did not reveal the hypothesized orientation performance.
Conclusions:
- Human non-visual homeward orientation abilities are not supported by current experimental evidence.
- The proposed link between geomagnetic influences and human navigation requires further investigation.
- Replication of Baker's findings under controlled conditions was unsuccessful.

01:30Magnetism
Magnets are commonly found in everyday objects, such as toys, hangers, elevators, doorbells, and computer devices. Experimentation on these magnets shows that all magnets have two poles: one is labeled north (N) and the other south (S). Magnetic poles repel if they are alike and attract if unlike. Moreover, both poles of a magnet attract unmagnetized pieces of iron.
An individual magnetic pole cannot be isolated. No matter how small, every piece of a magnet contains a north pole and a south...

01:28Magnetic Fields
A moving charge or a current creates a magnetic field in the surrounding space, in addition to its electric field. The magnetic field exerts a force on any other moving charge or current that is present in the field. Like an electric field, the magnetic field is also a vector field. At any position, the direction of the magnetic field is defined as the direction in which the north pole of a compass needle points.

01:19Magnetic Field Lines
The representation of magnetic fields by magnetic field lines is very useful in visualizing the strength and direction of the magnetic field. Each of the magnetic field lines forms a closed loop. The field lines emerge from the north pole (N), loop around to the south pole (S), and continue through the bar magnet back to the north pole.
Magnetic field lines follow several hard-and-fast rules:

01:25Magnetic Field due to Moving Charges
A stationary charge creates and interacts with the electric field, while a moving charge creates a magnetic field.
Consider a point charge moving with a constant velocity. Like the electric field, the magnetic field at any point is directly proportional to the magnitude of the charge and inversely proportional to the square of the distance between the source point and the field point. However, unlike the electric field, the magnetic field is always perpendicular to the plane containing the line...

01:19Magnetic Declination
Magnetic declination is the angle between true north, which aligns with the Earth's rotational axis, and magnetic north, which follows the direction of the Earth's magnetic field. This discrepancy exists because the magnetic poles do not coincide with the geographic poles. The value of magnetic declination depends on the observer's location on Earth and is subject to changes over time due to the dynamic nature of the Earth's magnetic field.The declination is called eastern when magnetic north...
01:22Local Attraction
Local attraction refers to disturbances in compass readings caused by magnetic influences from nearby objects such as metal fences, buried pipes, vehicles, buildings, power lines, or natural iron ore deposits. Small items like wristwatches, steel tools, or belt buckles can also interfere with the compass by creating local magnetic fields that distort the Earth's natural magnetic field. These distortions lead to inaccurate readings, posing navigation and land surveying challenges.Local...
